I don't think Epic on a Planeswalker does what you want it to. You do remember that Epic makes you copy the spell right? You could never get to use the -3.
Everything Matt says is also true.
Killane Ascendant
UUBBBRR
Planeswalker - Killane
Shroud
Killane is Indestructible
+3: Sacrifice all permanants you control, then exile your hand and graveyard. You must control at least 1 permanent and have at least 1 card in your hand to activate this ability.
- 2: Gain control of two target permanants.
-11: Exile your opponent's hand, graveyard, and library.
7
You realize the +3 would cause you to sacrifice Killane right?
ok, I didn't do a good job with this cycle. I think I can admit that.
Removed Epic and added- for the rest of the game, you cannot play spells.
edited wording on the sacrifice ability (all other permanents...)
why do you think planeswalkers should not have non-loyalty abilities? I understand it hasn;t been done, but why should it be impossible?
