I Am InvincibleRare Skill1Gain 10 (13) Block. At the end of your turn, if this is on top of your draw pile, play it

Spectrum Shift picks from every Colorless card you have unlocked that can be created in combat.

I Am Invincible changed twice: its Block rose from 9 (12) to 10 (13) on 19 March 2026, and since the 18 June 2026 update its end-of-turn play happens before you discard your hand.

How often each rarity appears

Each card in a reward rolls its rarity separately:

WhereUncommonRare
Normal fight37%3%, plus the rare card counter
Elite40%10%, plus the counter
Boss0%100%
Merchant37%9%

The rare card counter starts at -5%, rises by 1% for each card that is not rare and resets after a rare, so a rare Regent card like I Am Invincible is far less likely than an uncommon one like Spectrum Shift in any single reward. See reward odds.

Regent cards that use created cards

A card added to your hand by Spectrum Shift counts as created:
