Make A Stand

Anything that discards–Tormenting Voice, Catalog, etc.

Nissa’s Revelation

Scatter to the Winds

Engulf the Shore

TL;DR

Any spell which doesn’t have to select a target.

Cards with Delirium, as I posted here.
Until Yes/No are added, you can just turn off the auto-cast for the cards you don’t want to cast yet. But yea, sometimes you don’t know before making your move whether or not you’d want to cast them.

anything with awaken definitely. some are like 3 mana to draw a card 8 more summon island or whatever. If i miscalculated my cascade and really need that token I’m sol now because the spell is going off and i only got 5 mana.

Anything with delirium not so much because delirium is a reaction to circumstances.

For real. I can’t play Crush of the Tentacles in Kiora because I also play Bring to Light…

Not Forgotten
From Under The Floorboards
Any spell that creatures token creatures, in fact.

Spells like this are wasted if you play them when you have no space to put their creature tokens onto the board.

Just yesterday I accidentally cast it because it wasn’t in my hand until after I made the match and it got rid of my massive board of defenders. Still won, but it took a turn longer.

Engulf the Shore

If you think about it, shouldn’t all spells require confirmation?
