Trample, haste
When Tyrants of Bundan enters the battlefield, tap all lands target player controls. They don't untap during their controller's next untap step.

Whenever a land becomes tapped, its controller sacrifices it and creates a Treasure token.

Flying, haste
Venwyn, the Dragon's Fang can't block.
At the beginning of combat on your turn, you may pay {1}{R/G}. If you do, create a token that's a copy of target creature you control with mana value 3 or less, except it's not legendary and has haste. Exile that token at end of combat.

{T}: Add {C}.

Cycling {1}{R}{G} ({1}{R}{G}, Discard this card: Draw a card.)

Create a token that's a copy of target creature or land you control, except it has haste and “At the beginning of the end step, exile this permanent.” If a land you control was targeted this way, create two of those tokens instead.

• Target creature you control fights another target creature.
• Exile target artifact.
• Destroy target land. Its controller creates a tapped colorless land token named Lotus Spring with “{T}: Add one mana of any color.”
• Target player returns a land card from their graveyard to their hand.
