MTG Salvation

This card should never have been printed in the same set as Nyx Lotus. You can do all sorts of obnoxious things with this combo and cheap spells (e.g. have 3 devotion to blue and 1 open island: your opponent play a spell they don't think you can counter and you opt to untap your Lotus and use that mana to Sinister Sabotage them).

Sigiled Starfish. Of course. These cutesy references are getting to be a bit too much for me.
