While applying a replacement effect that modifies how a permanent enters the battlefield, another replacement effect may cause a player to mill cards or exile cards from the top of a library. In that case, any card that is entering the battlefield from that library won’t be included in that effect, even though those cards are in the library as the effect is applied.

Mill

For a player to mill a number of cards, that player puts that many cards from the top of their library into their graveyard.

A player can’t mill a number of cards greater than the number of cards in their library. If given the choice to do so, they can’t choose to take that action. If instructed to do so, they mill as many as possible. Similarly, the player can’t pay a cost that includes milling a number of cards greater than the number of cards in their library.

Dredge is a static ability that functions only while the card with dredge is in a player’s graveyard. “Dredge N” means “As long as you have at least N cards in your library, if you would draw a card, you may instead mill N cards and return this card from your graveyard to your hand.”

A player with fewer cards in their library than the number required by a dredge ability can’t mill any of them this way.

Replicate

Replicate is a keyword that represents two abilities. The first is a static ability that functions while the spell with replicate is on the stack. The second is a triggered ability that functions while the spell with replicate is on the stack. “Replicate [cost]” means “As an additional cost to cast this spell, you may pay [cost] any number of times” and “When you cast this spell, if a replicate cost was paid for it, copy it for each time its replicate cost was paid. If the spell has any targets, you may choose new targets for any of the copies.” Paying a spell’s replicate cost follows the rules for paying additional costs in rules 601.2b and 601.2f–h.

Stream of Thought is still on the stack while you choose cards in your graveyard to shuffle into your library. It can’t shuffle itself into your library.

You choose which cards to shuffle into your library while Stream of Thought is resolving. If you target yourself with Stream of Thought, you may choose any of the four cards that you put into your graveyard or any cards that were there before.

If you replicate Stream of Thought, the copies resolve before the original spell, so they can’t shuffle Stream of Thought into your library.

You’ll copy Stream of Thought for each time you paid its replicate cost, even if it’s countered.

The copies that replicate creates are created on the stack, so they’re not “cast.” Abilities that trigger when a player casts a spell won’t trigger.
