Mass-blink effects are what makes blink decks what they are. Eerie Interlude, Ghostway, Lae’zel’s Acrobatics – these cards can offer truly ridiculous amounts of value, as you blink five to 10 creatures with enter-the-battlefield effects and retrigger all of them. Not only that, but these cards also save the team from sweepers, as they return them at the beginning of the next end step, well after your opponent’s Supreme Verdict has resolved. Just make sure not to cast them in the end step directly preceding your turn, otherwise you won’t get the creatures back until your end step!
