Next: Stockpile (cost) (At the beginning of your upkeep, you may pay (cost). If you do, put a stockpile counter on this permanent)

Next:
Solve X - this permanent enters the battlefield with X puzzle counters. Whenever there are no puzzle counters on it, x happens

Since attacking outside combat isn't really a thing, im trying to rework it a bit be plausible. It will work a bit differently with things like trample or first strike.
Staticharged Baloth 1URG

5/5

Next:
Aethertouch - Whenever this creature deals damage to another creature, return that creature to it's owner's hand.
some ruling on this: it mostly works like deathtouch, except if you deal enough damage to that creature, it simply gets destroyed. It does not have the same interaction with trample as deathtouch. The bounce effect is put on the stack.

Exhaust: Add C to your mana pool (To exhaust, put an exhaustion counter on this permanent. You may exhaust only if the permanent is tapped and if there are no exhaustion counters on it.
