Splashing changeling cards like Bloodline Pretender, Gladewalker Ritualist, and Littjara Glade-Warden is also a solid option
A creature with Protection from a quality, let's say a colour for simplicity, can't be targeted by spells and abilities of that colour (like Shroud, that's regardless of who controls them)
They're easy to set up, quick to learn (mostly), and great for everything
Big thanks to Wizards for giving us a sweet preview card
Theyre designed to be opened two at a time, then combined to build a deck instantly
It requires setup, and the opponent isnt going to be sacrificing essential permanents right away, but this is the right spell when the right situation is on the board
