Card of the Week Poll #367: What's All the Type About?

{Explanation} Spellcards enter the battlefield with a number of spell counters on them equal to the number in the bottom right-hand corner. At the beginning of your upkeep, you remove a spell counter from each spellcard you control. Whenever you remove the last counter from a spellcard, you resolve any effects that may have resulted from its removal, then sacrifice the spellcard.

Most spellcards - especially at lower rarities - would only have effects that triggered on removing a spell counter from them. Some might trigger off of any time you remove a spell counter (or remove a counter period), or, like Dark Memory, have a static effect that doesn't interact with the spell counters at all.

The name is a reference to the Touhou attacks of the same name.

(Considering making this a subtype of enchantments for backwards-compatibility's sake.)

{Explanation} Main ruling in regards to the "Invocate-Stack": Only cards and effects that are on this stack can interact with this stack.
For example: "Counterspell can't counter spells on the "Invocate-Stack" cause it it put onto the regular stack and so on.

{Explanation} Signature is a new supertype that can go on any card type, and always has a corresponding planeswalker subtype. For as long as you control a planeswalker of a certain type, you can that planeswalker to search your library for a signature card of a matching type & put that card into your hand (normal planeswalker rules apply).

{Explanation} Partially inspired by Half-life, partially inspired by SCP-1104 (Nose Crab).

Symbiote is a creature exclusive supertype which denotes a creature that cannot survive without a 'host' creature to latch onto. All symbiotes have either the "symbotic" or "parasitic" keyword meaning they latch on to creatures you or an opponent controls respectively.
A creature with a symbote latched onto it has its power and toughness modified by the power and toughness modifiers noted where a normal creatures power and toughness would be.

{Explanation} Simple is a supertype for cantrips. Simple permanents have "When ~ ETB, draw a card" and simple instants and sorceries have "Draw a card" as a final spell ability.

Notably, you only draw one card off of the simple effect, even if multiple effects would give it the simple supertype. This makes it cool for providing extra card velocity to an archetype without having to cost around the possibility of duplicate effects.

{Explanation} The intent is that when either creature (or whatever else) is an illegal target, the whole hyperaura goes to the graveyard.
