You know "don't use FGs to determine balance"? Let me add a corollary: "Don't use EMs to determine balance." It's idiotic. Now, feral bond should really have its nerf undone anyway, NOT because of this change, but because it's UP. FB was only used so much because it was the only decent form of healing widely available. Miracle is a rare, so it wasn't used in beginner's FG decks, and it doesn't let you EM, so people didn't want to use it solely. With the FFQ nerf its only other use was nipped in the bid anyway.
Similarly, FFQ didn't really need the nerf. It was and is used so much because it was the only way to make lots of creatures. Even now, what else are you going to use? Pharaoh? Even more expensive, less damaging, and of a worse element. Aflatoxin? Requires two cards and more time to set up. Also doesn't do much damage. Low substitutability makes for high usage.
What he said, with slight remark: Feral Bond is UP only due to current metagame where building up an army in practice is possible only with Fractal. And you usually dont need Bond after Fractal.
Afla, creature generating creatures, or simply playing creatures from hand, is too slow for the game, so people generally take overpowered SoG.
Give us means to spam our board fast, even with 0|X creatures, and Feral Bond will be a super strong card. If we had a card that say generates 5 0|4 creatures on the field when played, hell yeah I'd use Feral Bond. Nothing else heals for up to 23 per turn, per Bond.
IMO, no need to lower cost on Bonds; I'd rather have a decent way to spam creatures. Maybe Flood will see some use then too.
