MUC with Polymorph

[Scrabble]

I have an upcoming legacy tournament where the meta is unknown for the most part, though I know it will be a small tourny, 8-12 most likely. I know there will be one Sligh/Blood Moon/Magus of the Moon deck, a crappy white weenie, I expect a UG madness, possibly thresh. Overall rather janky from what I know, though this may be misleading. My strategy going in to this was to pick a deck that could deal with many archtypes game one fairly easily. I figured the deck to do this with was MUC.

Here's the list:

4 Threads of Disloyalty
4 Powder Keg
3 Vedalken Shackles

4 Force of Will
4 Counterspell
4 Spell Snare
3 Prohibit
3 Forbid

3 Polymorph
1 Progenitus

4 Standstill

4 Faerie Conclave
4 Mishra’s Factory
4 Quicksand
12 Island

Card choices:
Threads of Loyalty- Overall a great creature control spell. Works especially well with Polymorph.

Powder Keg- MUC is great at dealing with anything due to it's large number of counters, this is for the cards that slip by. Helps with aggro.

Vedalken Shackles- Needed against aggro, works great with Polymorph.

Force of Will- goes in all blue decks

Counterspell- auto include

Spell Snare- questionable against unknown meta, though if it is anything like regular legacy meta, this card's a house

Prohibit- I think it's the next best counter, especially to help combat aggro. Chosen over mana leak/ rune snag due to it being relevant mid-late game. This spot could be daze with all of the spells I'll be wanting to play on my turn.

Forbid- I've always been a fan. Discards Progenitus to get it back in deck in a pinch. This slot could be brainstorm (which is not all that impressive without fetches which I don't have more than 1 of), or possibly Thirst for Knowledge if the Polymorphs were switched for Proteus Staff. Fact or fiction is another option but does not give a way to cycle Progenitus.

Polymorph- wincon, seems janky I'm sure, but it'll be fun and will help against aggro because post side I can have creatures that will clear the board like the red flyer that deals 3 damage to each creature or something to that effect (i think it's from portal?)

Progenitus- finisher

Standstill + Manlands- It's a good package on its own, the manlands work well with Polymorph.

Sideboard: This is something I desperately need help with as well. I was thinking Nevin. Disk's, possibly Douse because I will have a fairly good chance of playing against the Sligh/Moon deck, and also some extra counterspells for the combo matchup. Possibly stifle? Gaea's Blessing, or does MUC beat Solidarity?

Thanks for any suggestions.

Proteus Staff is ten times better than Polymorph in this deck

[Scrabble]

I've looked at it. I agree that it is if I'm running Tfk but I don't know if the extra 2 mana investment for an artifact, something so easily hated out, is worth it. I have thought about the possibility of putting the Staffs main deck and then siding them out when the artifact hate comes in, but I didn't follow up on it because it would make other card choices very awkward. I think I'd only run the Staffs with the Tfk but once the Proteus Staffs are sided out, the Thirst for Knowledges become sub par with only 7 other targets (Kegs, Shackles).

My big question is, what creatures are good sideboard cards. What creature will return enchantments or artifacts to hands to break a lock, what will clear the board, what is the best beat (Progenitus?)?

Stop playing Progenitus. It's cute and neat, but it's a bad play. Why not just play good ol' fashioned MUC? Play Call the Skybreaker as a finisher. Then you don't rely on drawing and resolving a Polymorph without them removing the creature in response. You have counters, but you can't expect to counter everything.

[Scrabble]

Well, I did a little play testing today, and you're right about the Polymorph. While I never had any trouble with resolving it as I always had counters, I found that there were times when I would much rather have had a Rainbow Efreet than the Polymorph with no target. I found the Polymorph to be useless at times when I didn't have a "gain control" spell, and the Rainbows would have definitely have helped to stop the aggro.

I still may play it just because it is a lot more fun, but I'll have to wait and see before the tourny starts to see if I'll need the Rainbows.

I played against a deck like this at the GP, it ran dominate as well, too funny.
