Heroic

[Vindog]

Can  {Oath of the Ancient Wood} trigger heroic ?

[Moneekahh]

No it would not trigger heroic. Because when its targets your creature, it's a permanent, not a spell.

[AkiraDeLaine]

Shouldn't it trigger when its cast? Not later on, but when it enters the battlefield?

[Moneekahh]

"Enters the battlefield" is part of the spell's resolution, so since the +1/+1 ability doesn't occur until it enters, at that point Oath is a permanent, not a spell, and thus can not trigger heroic.
