1. u can use exhustion effects on either players turn right???

example: if my opponent was going to kill my tracker, then i could activate mezzik's effect to kill tracker myself and do trackers atk as damage to my opponent????

2. with raddak doomsbringer (spelling???), i can pay as much as i want (cost x)...destroy a pet...(grimdon for example), then it does that much damage to my opponent???

just making sure im reading his effect right...so if i pay 10, i would do 10 right?!?!?

Correct for the first question, incorrect for the second.

Radak Doombringer pays cost X, where X is the cost of the pet. Grimdon has cost 1, so Radak can only exhaust 1 resource to activate his effect. The maximum dmg he can do at the moment is 6 with infernal.

thanks for clearing that up...that makes him seem alot less broken
