Deva Form

Deva Form is a Watcher rare power that grants 1 energy and draws 1 card at the start of each turn, but has the Ethereal keyword (disappears end of turn if not played). This makes it a high-reward power that must be played the turn it's drawn. Once active, Deva Form provides +1 energy and +1 draw every turn, which is incredible compounding value. +1 energy per turn is equivalent to one of the most powerful effects in the game, and drawing an extra card means even more options.

Deva Form requires drawing and playing it same-turn, which at 3 energy means you need a 3-energy turn — manageable in Calm-cycling builds. Once active, each turn it gives you 4 energy (base 3 + 1 from Deva) and 6 cards drawn (base 5 + 1), enabling significantly more plays per turn. Multiple copies stack, each adding +1 energy and +1 draw. The Ethereal downside is minimized through Scry (filter to find it) or simply having a deck that can afford 3 energy plays. Upgraded, Deva Form loses Ethereal entirely, making it consistent and removing all risk.
