Esper Sentinel

Whenever an opponent casts their first non-
creature spell each turn, draw a card unless that
player pays Variable Colorless, where X is Esper Sentinel's power.
In the Vault-City's heart, Esper Sentinel stands senti-
nel, vigilant eyes scanning the horizon. Celestial clock-
work melds with unwavering resolve, a guardian of
order and knowledge, safeguarding the future within
the looming apocalypse.
