Nimradell Watcher - A Mini Sweeper for a Rare or Mythic Creature

Nimradell watcher is one in a blue for a two one. Whenever you scry it gets plus one plus oh until end of turn and can't be blocked this turn. This trigger is only once each turn. I'm a little worried about it being an ex one yes that is for sure the unblockability of it at least like the fact that you don't have to worry about a mass tokens just running into this I think is better.
