Barrin, Tolarian Archmage While Mangara was looking to shake off the pillow fort descriptor, Barrin has built himself a bouncy castle. While Barrin and friends are certainly equipped to deal with opposing threats, the Archmage incentivizes us to prioritize bouncing our own threats instead
If the Treasures were generated per creature killed, this card would be busted, but you can trigger it every turn , not just yours, so playing smart means interaction on your opponent's turns can net you mana for your expended spell
She can bounce just about anything, and transform into a very threatening creature that makes your whole board scarier
Instead of doing her again in back to back sets, let's hit another good card for Commander that's heavily played too, but harder to make work, but more flexible
And then of course, the issue with this play is that if you use your resources to set up Klefki, you are not benching Ralts Drifloon (Scarlet & Violet): I actually think this card is better than most people think, as it is a very decent one-prize attacker that can deal with any other one-prize attacker in the format
