Played without support, it's a terrible card: spending 3 mana to cast a fragile creature, another mana to exile something, and then you need to wait at least another turn and pay 2 more mana and sacrifice it to cast a spell
Your Ward is increased to Ward 3, which is even harder to pay for
It mills you on every untap too
Assembled Ensemble and Killer Cosplay are two of the upcoming 'acorn cards', so will feature the new security stamp but will be illegal in all non-casual formats
If youre not so lucky as to have engines like Gemhide Sliver or Heritage Druid in your card pool, then this is another effect that can be worth looking for from your Commander
The game features brand new, original artwork and does an excellent job of capturing the characters in their Storyborn (classic) form while also adding fun twists for their Floodborn and Dreamborn variants
