WallHow it works & interactions with other cards

Whenever you cast your second spell each turn, draw a card, then create a 0/3 white Wall creature token with defender. At the beginning of combat on your turn, creatures you control with defender gain exalted until end of turn. (Whenever a creature you control attacks alone, it gets +1/+1 until end of turn for each instance of exalted among permanents you control.)

When Teyo enters, create a 0/4 white Wall creature token with defender and flying. +1: You and target opponent each draw a card. −2: Choose left or right. Until your next turn, each player may attack only the nearest opponent in the last chosen direction and planeswalkers controlled by that opponent.

Whenever this creature enters or attacks, create a 1/3 white Wall creature token with defender. Whenever a creature you control with defender dies, you may search your library for a basic land card, put that card onto the battlefield tapped, then shuffle.

Exile this Saga, then return it to the battlefield transformed under your control. (Transforms from Welcome to ....) Each Dinosaur card in your graveyard has escape. The escape cost is equal to the card's mana cost plus exile three other cards from your graveyard. (You may cast cards from your graveyard for their escape cost.) {T}: Add {G} for each Dinosaur you control.

Ravenous (This creature enters with X +1/+1 counters on it. If X is 5 or more, draw a card when it enters.) Shieldwall — Sacrifice this creature: Creatures you control with counters on them gain hexproof and indestructible until end of turn.

You may have this creature enter as a copy of any creature on the battlefield, except it's a Wall in addition to its other types and has defender. When you do, tap the copied creature and it doesn't untap during its controller's untap step for as long as you control this creature.

Juggernauts you control attack each combat if able. Juggernauts you control can't be blocked by Walls. Other creatures you control have base power and toughness 5/3 and are Juggernauts in addition to their other creature types.
