adrenaline doesn't really sync very well with the attack power of the creatures in this deck though. a frog (5 attack) with epinephrine played on it will do a total of 6 more damage, and the dragons (12 attack) will do 4 additional damage. Rustlers (1 attack) would do only 3 additional damage,
So basically...
Epinephrine
Pros: More attacks = stronger against bone wall
Cons: Less creatures = more susceptible to CC, more attacks = weaker to fire buckler
Matter of taste, all in all. I prefer the two out of place cockatrices.
Bonds could work, but I've never really run into a game where I find myself worrying about my health. The opponent's generally dead before me. ;P
