Homestuck: Mechanics

Upgrade: Put PARAM1 level counters on target equipment you control Used on 0 cards:

Upgrade works with the return of Level up, now on equipment cards, to let players unlock progressively more powerful equips--often as a combat trick

Prototype: Used on 0 cards:

Prototype is a one-time triggered effect that occurs the first time a creature enters the battlefield or dies under your control while you control the permanent with prototype, generally noting the qualities of the "prototyped" card that entered/died and synergizing with b/w blink and aristocrats.

Psionic: Used on 0 cards:

Psionic is a mechanic for instants & sorceries that deals damage to the caster, mainly in UR spellslinger/tempo/burn.

In card text or details pages, write the mechanic's code name (playtest name) between square brackets, like "[Crittercast]", "[Bushido 1]" or "[Delay 4 {2}{R}{R}]". It will be expanded to the mechanic's name plus reminder text, such as "Suspend 4 – {2} {r} {r} . (Rather than cast this spell from your hand,...)"
To expand a mechanic's name but not its reminder text, include parentheses at the end of the square brackets: "[Crittercast()]", "[Delay 9 {R}()]".
