mtg x ff booster box call upon classic summons MTG: Universes Beyond- Final Fantasy

Their effect could be unique or a new take on an old mechanic I like

Its the first round, and your opponent sidles into the seat across from you

I still get asked if well unban this card in Commander

Cards like Waterbender's Restoration, Extravagant Replication and Thassa, Deep-Dwelling repeatedly flickering your Aether Channeler and Riftwing Cloudskate gives you an incredible advantage because your opponents have to recast the same creature over and over (this is trickier in our era of powerful enters abilities, but still works)

If damage that can't be prevented is dealt to the target creature after Gatta and Luzzu's last ability resolves, you still put that many +1/+1 counters on it
