Our group has doubts about the interaction (or lack of) between Tendrils of Agony cast on a Tezzeret.
- Is Tezzeret a legal target for Tendrils as it's considered a player?
- If so, does Tendrils' loss of life make Tezzeret loose loyalty counters?
Thanks in advance!
If there is confusion, realize that when you normally would direct damage from a spell "at" the planeswalker, you're actually applying a redirection replacement effect.
212.9g If noncombat damage would be dealt to a player by a source controlled by an opponent, that opponent may have that source deal that damage to a planeswalker the first player controls instead. This is a redirection effect (see rule 419.6c) and is subject to the normal rules for ordering replacement effects (see rule 419.9). The opponent chooses whether to redirect the damage as the redirection effect is applied.
A planeswalker isn't a legal target for spells that target players, as it is not a player... it just plays one on TV sometimes.
