Yargle, Glutton of Urborg

Flying When Uldaros Theorix enters, if you cast him, exile up to one target nonland card of each card type from your graveyard. Copy those cards. You may cast any number of spells with total mana value 6 or less from among the copies without paying their mana costs. (Permanent spells cast this way become tokens.)

When Tinybones enters, each opponent discards a card. Whenever a player discards one or more cards, Tinybones deals 1 damage to each opponent.

Flying Prowess, prowess (Whenever you cast a noncreature spell, this creature gets +1/+1 until end of turn twice.) Whenever Ruric Thar becomes the target of a spell or ability an opponent controls, draw a card.

This creature enters prepared. (While it's prepared, you may cast a copy of its spell. Doing so unprepares it.) Threshold — This creature gets +1/+1 as long as there are seven or more cards in your graveyard.

This land enters tapped unless you control two or more other lands. T: Add R or G.

Ward 2 (Whenever this creature becomes the target of a spell or ability an opponent controls, counter it unless that player pays 2.) 6GG: This creature gets +4/+4 and gains trample until end of turn.

Flash When this creature enters, empower Jace 3. (Put three loyalty counters on a Jace token you control. If you don't control one, first create a blue Jace planeswalker token with "[−1]: Surveil 1" and "[−3]: Draw a card.") U, Sacrifice this creature: The next spell you cast this turn can't be countered.

Trample Traxos doesn't untap during your untap step. Whenever you cast an artifact or creature spell, untap Traxos.
