Enchant land
Enchanted land has “{T}: Exile the top card of your library. If it's a nonland card, you may cast that card this turn.”

Copy target instant or sorcery spell you control. You may choose new targets for the copy.

Each creature has haste and “At the beginning of combat on your turn, choose an opponent at random. This creature attacks that player this combat if able.”

Choose one —
• Creatures you control get +2/+0 until end of turn.
• Creatures your opponents control can't block creatures with less power this turn.

Untap each creature you control. After this main phase, there is an additional combat phase followed by an additional main phase. At the beginning of your end step, sacrifice each creature you control that attacked this turn.

Each player discards their hand and sacrifices all permanents they control, draws seven cards, then abounds seven times. (To abound, you may cast a spell that costs less than this from your hand without paying its mana cost.)

As an additional cost to cast this spell, sacrifice a creature.
Create X Treasure tokens, where X is the sacrificed creature's mana value.
