Hrm...Concerning this card: Cast the ability, and the creature gets the boost right?
Is it a permanent bonus, or must it be recast every turn?
If recast every turn, that actually cuts out the adrenaline synergy, as it would only apply one time, and then vanish, leaving the other attacks un boosted.
However, if it were a repeatable cast, like Rustler, then assuming you can't just dump quanta into the creature and it apply in one attack (possibly abusable!), it would be possible to actually cast and then have quanta wasted via the creature dying before the 'magic attacks' could be used.
