Targeted Hexproof by mistake

[mickeven]

What happens if an opponent targets a creature I control that has hexproof with a  {Doom Blade}, but the opponent controls other creatures that are legal targets? Does the spell fizzle, or does he have to choose of of his creatures as a target, or can he just let it do nothing, or does the play just gets rewinded (Doom Blade back to his hand, lands untapped)?

i know they cant choose that target, but thats why I ask, what if they do by mistake, tap the mana and "casts" the spell targeting the hexproof thing, while there are other legal targets on the battlefield?

[mickeven]

okay got it. thanks bud!

At most events, including Competitive REL, we would just rewind to just before the casting, as that's when the illegal action was taken.  Warning given and a reminder to play more carefully.

This. Any time there's an illegal action state is rewound until before the action if possible.

But announcing targets is after announcing the spell. Why wouldn't it rewind to declaring targets instead of removing the whole action of casting it?

For the same reason if he announced it and realized he didn't have enough mana:  one part of the process being illegal renders the whole process illegal.  It's also incredibly unreasonable to play a game of 'gotcha!' And force them to kill their own thing.  Either way, they're at a disadvantage as their opponent now knows the identity of a card in their hand.

{{remilllo}} for the win! I wasn't thinking of it as a gotcha type thing, but just that potentially for pro rel that if you attempted to cast it you had to try to cast it if possible. But i understand and thank mate!
