Welcome to Valley

Whenever a creature you control becomes blocked, round both its power and toughness up to the nearest 5. (A creature with 5 power would round up to 5.) Whenever Chaos ensues, Amass Fans 5. (Put five +1/+1 counters on an Army you control. It's also a Fan. If you don't control an army, create a 0/0 red Fan Army creature token first.)

Raid — At the beginning of your second main phase, for each player dealt combat damage this turn, you get a point counter and create a 2/2 black Pirate creature token with menace. Whenever you planeswalk away from here, each player with the most point counters or tied for the most point counters creates three Treasure tokens and draws three cards. Then remove all point counters from each player. Whenever Chaos ensues, proliferate for each Pirate you control.

When you planeswalk here and at the beginning of your upkeep, create a Black Lotus artifact token. Whenever Chaos ensues, each player draws a card for each artifact token they control.

When you encounter this phenomenon, starting with the next player in turn order, that player chooses a permanent type. The next player chooses a number between 1 and 10. The next player chooses a keyword counter. Then reveal and resolve the following ability with those words. (don't reveal the second ability before the words have been chosen!) Each player creates a token that's a copy of a [permanent] and puts [number] +1/+1 counters on it. If it's not a creature, it becomes a 0/0 creature in addition to its other types. It enters with [keyword] counter.

When you encounter this phenomenon, open a Magic: The Gathering booster pack and shuffle it without looking at its contents. Those cards become the booster deck. You become the monarch. For the rest of the game, at the beginning of the monarch's end step, that player draws a card from the booster deck. They may spend mana of any type to cast those cards. (Then Planeswalk away from this phenomenon.)

Whenever you attack, create a Pin token attached to target attacking creature you control. It's an Pin Aura enchantment with enchant creature and "Enchanted creature gets +1/+1." Whenever Chaos ensues, each opponent loses X life, where X is the total number of pins attached to you and creatures you control. (This includes pins on your backpack.)

When you planeswalk here and at the beginning of your upkeep, fold this plane in half. Draw cards equal to the number of times it's been folded. If you can't fold it, planeswalk. Chaos: Completely unfold this plane. Each opponent discards two cards.

Nonbasic lands are Wastes. Whenever you tap a permanent for C, add an additional C. Whenever chaos ensues, choose one — • Draw four cards. • Destroy target permanent. • You may return target creature card from your graveyard to the battlefield.
