(Yes, the original playtesters did truly playtest the game.) This brings up the first question about milling
it can hurt itself and others randomly
In any deck with non-Angel creatures this one is kinda cracked, but do keep in mind: you want more than 30 creatures, lots of EtBs, and plenty of self-sacrifice or sacrifice outlets to truly rinse this card for all it is worth
While both Blade Splicer and Restoration Angel could show up in generic control or midrange decks, their main home is some sort of blink shell
Also, white does get some artifact creature producers that can start to bridge the gap: Black I don't really know
The new cards will follow the same type of guidelines as the Pokemon ex cards, but will no longer take damage from attacks if they are on the Bench
