Welcome to… - 1GG
Enchantment - Saga
1 - For each opponent, up to one target noncreature artifact becomes a 0/4 Wall artifact creature with defender for as long as you control this saga
2 - Create a 3/3 Green Dinosaur creature token with trample. It gains haste until end of turn
3 - Destroy all Walls. Exile this Saga, then return it to the battlefield transformed under your control

Legendary Land
Each Dinosaur card in your graveyard has Escape. The Escape cost is equal to its mana cost plus exile 3 other cards from your graveyard.
Tap: add G for each Dinosaur you control

I’d really like to see this get a Universes Within version sometime soon because it seems amazing for Dinosaur decks but the creative feels too weird to me
