Stronghold Furnace

All creatures have "T: Add GG." Whenever chaos ensues, untap all creatures you control.

When you planeswalk to Quicksilver Sea and at the beginning of your upkeep, scry 4. (Look at the top four cards of your library, then put any number of them on the bottom and the rest on top in any order.) Whenever chaos ensues, reveal the top card of your library. You may play it without paying its mana cost.

Whenever a nonblack card is put into a player's graveyard from anywhere, that player loses 1 life. Whenever chaos ensues, each opponent discards a card.

Creatures without flying or islandwalk can't attack. Whenever chaos ensues, until a player planeswalks, you can't lose the game and your opponents can't win the game.

Whenever a creature leaves the battlefield, its controller draws a card. Whenever chaos ensues, return target creature you control to its owner's hand.

Whenever a creature you control attacks a player, for each other opponent, you may create a token that's a copy of that creature, tapped and attacking that opponent. Exile those tokens at the beginning of the next end step. Whenever chaos ensues, you may sacrifice any number of creatures. If you do, Kharasha Foothills deals that much damage to target creature.

You may play any number of lands on each of your turns. Whenever chaos ensues, target red, green, or white creature you control gets +1/+1 until end of turn for each land you control.

Creatures can't block. Whenever chaos ensues, draw a card for each land you control.
