This card has a second half to it, though, which, while interesting, adds quite the additional cost. The new Awaken mechanic seems a bit expensive to me when it comes to risk vs reward. Turning one of your lands into a 0/0 Elemental with 4 +1/+1 counters just seems really gimmicky to me, and at 5BB, I’m not sure I’d be making that sort of investment in Constructed. I like the flavor here, certainly, and getting the card’s effect plus 4 colorless mana for a 4/4 creature certainly is properly costed.
It’s probably true that Hero’s Downfall was perhaps a bit too good in some cases, so perhaps this card is a bit more “fair” while also having some additional flavor added to it in the process. I just don’t feel like Awakening a land is something I’d want to do while playing this card, but that’s my opinion. What do you think of this card?
