I'm more of a Johnny than a Spike at heart, so I always love these threads:
1.) Was playing shops against a top dredge player. They were rocking the Arabian Nights City of Brass over Mana Confluence (which I can't fault, since Arabian Cities of Brass are about 10000x coooler). I had him low on life, but couldn't put it away. Was able to get a tangle wire out and metamorph it. He died to his Cities getting tapped. I think he changed to Mana Confluence shortly after.
2.) Was playing shops against Mentor. He put down an unprotected Mentor. I was able to Metamorph it, Ballista the original Mentor, and then drop a few artifacts into play. Got to taste the enjoyment of swinging with Mentor tokens. Not sure it was the "optimal play", but damned if i wasn't going to do it anyway.
My closest call:
Was playing Shops against Oath. Oath player was down to the last three cards in his deck and a depleted hand before he got Griselbrand into play. I had a Jester's Cap in hand, ready to deck him, but came up one mana short of activating it. He won the game next turn.
Personal gripe: Why they made Mana Confluence strictly better than City of Brass I'll never forgive.
