AI 🤖 Find me cards equivalent to: Pollywog Symbiote

Equivalent cards to Pollywog Symbiote (blue, creature, cost reduction/mutate synergy):
1. Cloud Key – Reduces casting cost for chosen type (includes creatures).
2. Herald of Kozilek – Reduces colorless spell costs.
3. Jace's Sanctum – Reduces instant/sorcery costs, but not creature specifically.
4. Heartless Summoning (black, but worth mentioning)—reduces creature cost.
5. Vodalian Arcanist – Reduces cost of kicker spells.

There are few blue creatures with direct generic cost reduction for creatures, so Pollywog Symbiote is fairly unique but Cloud Key is a strong alternative.
Reason: Pollywog Symbiote specifically reduces creature spells and has mutate synergy, which is very rare in blue.

  • The cost reduction applies only to generic mana in the cost of spells of the chosen type you cast.
  • To determine the total cost of a spell, start with the mana cost or alternative cost you're paying (such as a flashback cost), add any cost increases (such as kicker costs), then apply any cost reductions (such as that of Cloud Key's ability). The mana value of the spell is determined by only its mana cost, no matter what the total cost to cast that spell was.

    Abilities/Keywords

    Devoid

    Rules

  • A card with devoid is just colorless. It's not colorless and the colors of mana in its mana cost.
  • Cards with devoid use frames that are variations of the transparent frame traditionally used for Eldrazi. The top part of the card features some color over a background based on the texture of the hedrons that once imprisoned the Eldrazi. This coloration is intended to aid deckbuilding and game play.
  • Devoid works in all zones, not just on the battlefield.
  • Herald of Kozilek's last ability can't reduce the amount of colored mana you pay for a spell. It reduces only the generic component of that mana cost.
  • Herald of Kozilek's last ability doesn't change the mana cost or mana value of any spell. It changes only the total cost you actually pay.
  • If a card loses devoid, it will still be colorless. This is because effects that change an object's color (like the one created by devoid) are considered before the object loses devoid.
  • If a colorless spell you cast has {X} in its mana cost, you choose the value of X before calculating the spell's total cost. For example, if that spell's mana cost is {X}, you could choose 5 as the value of X and pay {4} to cast the spell.
  • If there are additional costs to cast a spell, or if the cost to cast a spell is increased by an effect, apply those increases before applying cost reductions.
  • Other cards and abilities can give a card with devoid color. If that happens, it's just the new color, not that color and colorless.
  • The cost reduction can apply to alternative costs.

    Rules

  • An ability that triggers when a player casts a spell resolves before the spell that caused it to trigger. It resolves even if that spell is countered.
  • Effects that reduce the generic mana cost of a spell (such as that of Pollywog Symbiote) can’t reduce that spell’s colored mana requirements.
  • Players can cast spells and activate abilities after the triggered ability resolves but before the spell that caused it to trigger does.
  • Pollywog Symbiote’s first ability applies to creature spells you cast that have mutate even if you don’t cast them for their mutate cost. Similarly, its second ability triggers even if the creature spell with mutate was cast for a cost other than its mutate cost.
  • You draw a card and discard a card all while Pollywog Symbiote’s ability is resolving. Nothing can happen between the two, and no player may choose to take actions.
