Overview
Spellbinder is an A Tier support card that triggers the Crawler's ability one additional time at cost 0. The 0-mana cost allows insertion anywhere in the combo staircase without disrupting flow. Dual role: Unholy Vespers evolution component + standalone ability-doubling power.
On crawlers with strong active abilities (Arca, Porta, Clerici), Spellbinder doubles the impact of the ability trigger — mana generation, Amount increase, healing, etc.
Evolution Use
Spellbinder + King Bible → Unholy Vespers
In Unholy Vespers runs, secure both. Whichever arrives first, hold and wait for the other.
Why Run Spellbinder
- Cost-0 Crawler ability extra trigger (doubles ability impact)
- Required Unholy Vespers evolution component
- Strong synergy with ability-dependent crawlers (Arca, Porta, Clerici)
- 0-cost insertion anywhere in combo chain
Synergies
- King Bible: direct Unholy Vespers evolution component
- Arca: mana generation ability fires twice = double mana supply
- Clerici: healing ability fires twice = double recovery
- Porta: Amount increase ability fires twice = Amount+2 per turn
