Ability word that counts colors among permanents you control and cards in your graveyard. Encourages you to play spells of as many colors as possible, which is made easier by all the twobrid cards.

Proxy: As an additional cost to cast this, tap an untapped creature you control that shares a color with it. Used on 0 cards:

Sort of like an anti-Convoke. The effect of Proxy spells increase with the CMC of the tapped creature, encouraging you to tap a single large creature. Combos with twobrid creatures.

.: You choose any number of permanents and/or players with counters on them, then give each another counter of a kind already there. Used on 0 cards:

Returning mechanic. Useful with thauma counter shenanigans.

.: Remove two thauma counters from permanents you control to add {1}

to your mana pool. Used on 16 cards: Cresting Marsh, Surging Peak, Singing Woods, Thaumaton Quartz, Lancing Sands, Thrashing Cay, Sand Waker, Marsh Waker, Peak Waker, Wood Waker, Cay Waker, Caywater Counsel, Sandskin, Mind Marsh, Peak of Treason, Woodbreak

Thauma counters are the creature counter for this block. They are referenced by a lot of things and can be traded in for colorless mana.

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}()]".
