As you get more experienced and more advanced with the deck, some of these calls will change based on a wide variety of factors...but this is a good starting guide.
Stoneblade
[When you are on the] Play: Brainstorm
[When you are on the] Draw: Hold.
If you're on the play, try to disrupt a shaky keep by taking Brainstorm, which also makes your future Therapies better. If you're on the draw, you want to hold your Therapy so that you can either use it after they Stoneforge, or on turn 3 naming Jace TMS.
RUG
Play: Stifle
Draw: Stifle
It's our number one enemy in this matchup. If they don't have it, congrats, you have information and the go-ahead for Explorer to ramp past their tempo. Also keep in mind that they give you information on their hand from Delver. Write it down.
Maverick
Play: Noble Hierarch
Draw: Knight of the Reliquary
Mid-late game, it's usually best to name Green Sun's Zenith or Swords to Plowshares, unless you have information from Fauna Shaman or some such. Hierarch on the play can really disrupt them, because maverick players tend to lean on their Hierarchs a lot more than they should...especially with like Savannah Hierarch x2 Cradle [cards] type of hands. You can really punish them for that. Also watch out for Mindcensor, although usually they're just going to flash it out in resp. to Therapy just in case.
High Tide
Play: Brainstorm
Draw: High Tide
If you whiff on High Tide, use your own judgment based on the information you get. Postboard, if you can bin a Time Spiral for Extirpate, that's sex in a can.
TES and ANT
Play: LED
Draw: Dark Ritual
Ideally you want to name mana on the call, and then business on the flashback. Doesn't always work that way though...be prepared to be flexible here.
Doomsday
Play: Doomsday
Draw: Doomsday
I don't know enough about this matchup to know if this is actually correct or not. I guess you could name Top on the play and annoy them that way. But at the end of the day if you can hit their Doomsday, the matchup gets awkward for them and gives you more time to disrupt/beat. This is a really awkward matchup in general.
Goblins
Play: Lackey
Draw: Matron
You could also make a case for Ringleader on the draw.
Merfolk
Play: Vial
Draw: Master of the Pearl Trident [Lord of Atlantis]
I've seen lists running like 4 Master 2 Lord, so you probably want to call Master. Midgame, name Phantasmal Image. You don't want them copying a Grave Titan.
Elves
Play: Glimpse
Draw: Glimpse
Glimpse is public enemy number one. Symbiote is a good take too, since it helps them recover from Deed and fuels a lot of their engines.
Nic Fit mirror (assuming G/B or GBw [Swords/Titan version, no Rector]
Play: Sensei's Divining Top
Draw: Green Sun's Zenith
The mirror of this deck is pretty awkward. Top is definitely right on the play. GSZ is probably their best card on the draw, so I'd go for that, but that's much more questionable. Use your own discretion.
Reanimator
Play: Reanimate
Draw: Animate Dead
To my knowledge, most reanimator decks are shaving Exhume. If you have reason to believe that he's running Exhume, name that -- Animate Dead can at least be killed with Deed. Note: if you're on the play postboard, there's a good chance you want to name Thoughtseize to protect an Extirpate. This is only if you have an Extirpate in hand though IMO. Remember to keep an eye out for Show and Tell. S&T is slower here though, since they only run like 2 City of Traitors. You can take that on the flashback. Also if you have an Extirpate, don't be afraid to name Griselbrand and then make them all go away.
Sneak/Show
Play: Show and Tell
Draw: Griselbrand
Miracles
Play: Brainstorm
Draw: Counterbalance
Belcher
Play: LED
Draw: Seething Song
This is awkward and possibly incorrect. It might be that naming Burning Wish or Belcher itself is just better. Nothing about this matchup is good, though, so it probably doesn't matter. I'd say if you take their main mana producers, it should slow them a few turns while you get more discard online to take their business....but unlike ANT/TES, they run a pisston of mana, so I don't know.
Dredge
Play: LED
Draw: Breakthrough
BUG Delver
Play: Stifle
Draw: Stifle
Same as RUG here, really.
BUG Control
Play: Brainstorm
Draw: Hold
Same as with Stoneblade.
Burn
Play: Lightning Bolt
Draw: Fireblast
Midgame, look at their graveyard and see what burn spells they've used. Keep in mind that Burn tends to run as many 4-ofs are possible, so you can maximize your chances by naming a burn spell that they haven't used yet.
U/R Delver
Play: Delver
Draw: Daze
Daze is an odd name here. The thing is that you don't really want to get Dazed while you're setting up. It's also a blue card, which means if they have Force in hand, their Force gets worse if you hit (and if they do, you take it on the flashback). You just want to get to Thragtusk here, pref. with Nightmare active. Daze is a serious hindrance to that plan, because most of the time you're going to have to GSZ for exact. Watch out for Spell Pierce too.
Death and Taxes
Play: Vial
Draw: Phyrexian Revoker
Deed is our best card here. We know and they know it, and Revoker is their answer to it. Keep an eye out for Mangara, too....don't let that happen if you can avoid it.
MUD
Play: Grim Monolith
Draw: Forgemaster
Take this with a grain of salt....if you're on the draw and they lead like Seat of the Synod -> Voltaic Key, or just 1-mana land pass, you still name Monolith. Monolith is the most dangerous card in their deck, with Metalworker as a close second. If you can take away their fast mana, the deck tends to implode on itself a lot.
