'Earth' cards

When you planeswalk to Amy's Home and at the beginning of your upkeep, you may exile a nonland card from your hand with a number of time counters on it equal to its mana value. If it doesn't have suspend, it gains suspend. Whenever chaos ensues, time travel. (For each suspended card you own and each permanent you control with a time counter on it, you may add or remove a time counter.)

When you planeswalk to Antarctic Research Base and at the beginning of your upkeep, investigate. Whenever chaos ensues, put X +1/+1 counters on target creature you control, where X is the number of artifacts you control. It becomes a Plant in addition to its other types.

At the beginning of combat on your turn, exile up to one target creature. Return it to the battlefield under its owner's control at the beginning of the next end step. When chaos ensues, cards can't enter from exile this turn. Then planeswalk.

Whenever a player casts a historic spell, that player draws a card. (Artifacts, legendaries, and Sagas are historic.) Whenever chaos ensues, return target historic card from your graveyard to your hand.

Still Point in Time - All spells have split second. (As long as a spell with split second is on the stack, players can't cast spells or activate abilities that aren't mana abilities.) Whenever chaos ensues, Lake Silencio deals 6 damage to target creature an opponent controls. If a creature dealt damage this way would die this turn, exile it instead.

At the beginning of combat on your turn, until end of turn, noncreature artifacts you control become 3/3 Vehicles in addition to their other types and gain flying, haste, and crew 1. Whenever chaos ensues, create a Treasure token and a 2/2 white Alien creature token.

At the beginning of your upkeep, target opponent draws a card and creates a Treasure token. Whenever chaos ensues, create a 2/2 white Alien creature token. When you do, tap target nontoken creature an opponent controls. Put a stun counter on it. (If a permanent with a stun counter would become untapped, remove one from it instead.)

When you planeswalk to Pompeii and at the beginning of your upkeep, put an eruption counter on it. Whenever you roll a blank on the planar die, scry 2. Then put an eruption counter on Pompeii. When chaos ensues, Pompeii deals damage to each creature and each player equal to the number of eruption counters on Pompeii. Each player sacrifices a land of their choice. Then planeswalk.

At the beginning of combat on your turn, up to one target creature you control becomes a copy of target creature an opponent controls. Will of the council - Whenever chaos ensues, starting with you, each player votes for a creature you don't control. Exile each creature with the most votes or tied for most votes.

Each creature card in your graveyard has scavenge. The scavenge cost is equal to its mana cost. (Exile a creature card from your graveyard and pay its mana cost: Put a number of +1/+1 counters equal to that card's power on target creature. Scavenge only as a sorcery.) Whenever chaos ensues, create two 1/1 white Warrior creature tokens.

When you planeswalk to UNIT Headquarters and at the beginning of your upkeep, create a tapped 1/1 white Soldier creature token. Whenever chaos ensues, put a +1/+1 counter on each creature you control.
