Green Slime rulings
Activated abilities contain a colon. They're generally written “[Cost]: [Effect].” Some keywords are activated abilities and will have colons in their reminder text.
Triggered abilities use the word “when,” “whenever,” or “at.” They're often written as “[Trigger condition], [effect].”
Mana abilities don't use the stack and can't be responded to, so they cannot be countered this way.
Because exiling a card with foretell from your hand is a special action, you can do so any time you have priority during your turn, including in response to spells and abilities. Once you announce you're taking the action, no other player can respond by trying to remove the card from your hand.
Casting a foretold card from exile follows the timing rules for that card. If you foretell Green Slime (or an instant card), you can cast it as soon as the next player's turn. In most cases, if you foretell a card that isn't an instant (or doesn't have flash), you'll have to wait until your next turn to cast it.
If you're casting a foretold card from exile for its foretell cost, you can't choose to cast it for any other alternative costs. You can, however, pay additional costs, such as kicker costs. If the card has any mandatory additional costs, those must be paid to cast the spell.
Green Slime keyword rules
Flash Rule 702.8
Flash is a static ability that functions in any zone from which you could play the card it’s on. “Flash” means “You may play this card any time you could cast an instant.”
Multiple instances of flash on the same object are redundant.
Foretell Rule 702.143
Foretell is a keyword that functions while the card with foretell is in a player’s hand. Any time a player has priority during their turn, that player may pay {2} and exile a card with foretell from their hand face down. That player may look at that card as long as it remains in exile. They may cast that card after the current turn has ended by paying any foretell cost it has rather than paying that spell’s mana cost. Casting a spell this way follows the rules for paying alternative costs in rules and –h.
Exiling a card using its foretell ability is a special action, which doesn’t use the stack. See rule , “Special Actions.”
If an effect refers to foretelling a card, it means performing the special action associated with a foretell ability. If an effect refers to a card or spell that was foretold, it means a card put in the exile zone as a result of the special action associated with a foretell ability, or a spell that was a foretold card before it was cast, even if it was cast for a cost other than a foretell cost.
If an effect states that a card in exile becomes foretold, that card becomes a foretold card. That effect may give the card a foretell cost. That card’s owner may look at that card as long as it remains in exile and it may be cast for any foretell cost it has after the turn it became a foretold card has ended, even if the resulting spell doesn’t have foretell.
If a player owns multiple foretold cards in exile, they must ensure that those cards can be easily differentiated from each other and from any other face-down cards in exile which that player owns. This includes knowing both the order in which those cards were put into exile and any foretell costs other than their printed foretell costs those cards may have.
If a player leaves the game, all face-down foretold cards that player owns must be revealed to all players. At the end of each game, all face-down foretold cards must be revealed to all players.
