mtg playtest cards scryfall Secret Lair/Playtest Tibalt the Chaotic · Mystery

The deck is uniquely built since it cannot play any card which costs less than 2-mana due to the Cascade mechanic, so it profits from the multiple free spells in the format

(2017-09-29) If an effect causes a Vehicle to become an artifact creature with a specified power and toughness, that effect overwrites the Vehicle's printed power and toughness

You're simply going to have more games where your deck does the things it was built to do, even if those things are silly, whimsical or just plain goofy

If Teyo, Geometric Tactician's last ability and another similar effect disagree on which direction three or more players may attack, players can't attack at all

Set will also have a bundle and Collector Boosters

Otherwise, Im not sure what it has to offer
