I really haven't had any problems getting EMs against False Gods after the Bond change, unless poison is involved. Only a few FGs use poison, and at least one of them is difficult to beat with my deck anyway.
If you have shards, EM is all about clearing any enemy creatures with momentum, then timing a good shield. If your shards are taking longer than expected to heal you back and you're about to make the kill, a Sundial can buy you a turn to heal to full first.
I pack Phase Shields, Bone Walls, and Permafrost in my FG rainbow - the first two can be easily used to keep you at 100 for the last turn.
