Cavern of Souls

First strike At the beginning of combat on your turn, if another Human entered the battlefield under your control this turn, create two 2/2 red Human Knight creature tokens with trample and haste. Then if you control six or more Humans, draw a card.

Partner with Sam, Loyal Attendant Vigilance Whenever Frodo attacks, if you gained 3 or more life this turn, the Ring tempts you. Then if Frodo is your Ring-bearer and the Ring has tempted you two or more times this game, draw a card.

Will of the council — At the beginning of combat on your turn, if another Elf entered the battlefield under your control this turn, starting with you, each player votes for dominion or guidance. If dominion gets more votes, the Ring tempts you, then you put a +1/+1 counter on your Ring-bearer. If guidance gets more votes or the vote is tied, draw a card.

When you cast this spell, amass Orcs 5, mill five cards, then return a creature card from your graveyard to the battlefield. Trample Whenever a commander an opponent controls dies, the Ring tempts you.

Vigilance, lifelink When Aragorn enters, you become the monarch. Whenever Aragorn attacks, up to one target creature can't block this turn. If you're the monarch, creatures can't block this turn.

Whenever you cast a spell with mana value 5 or greater, each opponent reveals the top card of their library. If any of those cards shares a card type with that spell, copy that spell, you may choose new targets for the copy, and each opponent draws a card. Otherwise, you draw a card. (A copy of a permanent spell becomes a token.)

Partner with Frodo, Adventurous Hobbit (When this creature enters, target player may put Frodo into their hand from their library, then shuffle.) At the beginning of combat on your turn, create a Food token. (It's an artifact with "2, T, Sacrifice this token: You gain 3 life.") Activated abilities of Foods you control cost 1 less to activate.

Whenever you cast a noncreature spell, amass Orcs X, where X is that spell's mana value. (Put X +1/+1 counters on an Army you control. It's also an Orc. If you don't control an Army, create a 0/0 black Orc Army creature token first.) Goblins and Orcs you control have ward 2.
