Hi!
First things first, the mods and users in this forum value punctuation relatively high, you might want to check out the forum rules. Also check out the hyperlink function: [cards]Ichorid[/cards.] without the . =
Ichorid, you just have to put [cards] at the beginning and [/cards.] without the . at the end of your decklist e.g.
Regarding your list:
I strongly recommend the 4th Therapy maindeck. I would also use a third Ichorid, but that's more a matter of taste( Though having 3 Ichorids maindeck makes room in the sideboard since you don't have to run 1-2 Ichorids in your board anymore)I would cut a Land+x for it if you want to make this change, it's better to test it first ofc.
Regarding your board:
2 Firestorm and 3 Nature's Claims do almost nothing, I'm sorry. Exspecially Nature's Claim, you really cannot afford not to have it if your opponent slams a Leyline or such things, so a 4th Claim might be good.
2 Firestorms is a bit random, too I think, also Firestorm is a bit worse in LED builds, since you don't want to board them out against Maverick, still you want to bring in Firestorms and seriously, having a hand of Firestorm, LED,LED, Thug, Troll, Land, Looting or so makes Firestorm less good. Still it CAN be good,though.
I'm curious why you chose to run Faerie Macabre in your board, care to elaborate?
