Entwine, targetless modes, and all targets are illegal #9381
Description
Entwine is currently bugged for spells that have modes without a target.
If the player casts a spell entwined, and all targets become illegal, the untargeted modes still resolve.
None of its effects should happen.
Also, in some cases, it uses the targeted mode's target for the untargeted effect.
A good example is Abuna's Chant, which apparently heals the controller of the target instead of 'you'. I think it's best that all cards with entwine are double-checked. (as well as cards with similar abilities or that can have more than 1 mode chosen)
The wrong target thing is a card-script issue (the mode does not force 'you' in it, so it defaults to the target's controller).
It resolving without legal targets, however, is a bug in the entwine code.
Steps to reproduce the behavior:
- Cast Abuna's chant entwined targeting an opponent's creature.
- Destroy the creature with some other effect.
- Abuna's chant will resolve, healing the opponent.
Abuna's Chant should do nothing, since all targets are illegal, and it most certainly should not heal the opponent even if the target were legal.
