lame i responded and pbn kicked me off so it didn't post. and now i don't remember what i had said.
with cascade, anything populate seems to be the way to go from the new sets. the more cards you can get out that activate on entry, the better. i don't know too many of the newer cards because we're playing sealed friday and i am a stickler for looking up spoilers. so i really only know the cards people post on facebook. like the three drop gruul planeswalker, domri. his final ability gives trample, haste, hexproof, and doublestrike to all of your creatures.
shocklands are back, so that should solve a lot of multicolor decks mana issues to pump out more cards. but with rtr anyways, there is so much going on for multi color decks that i feel like the transition back into solid colors will feel so empty.
i have one solid deck now and it's my beast deck. but even now i'm considering splashing white thanks to thragtusk and populate.
