Nearest-era rulings (Tengu, Sept 2011) — no REDU-specific archive exists.
Card effect (current official text)You can Tribute 1 "Eva Token" to Special Summon this card from your hand. While this card is in your Graveyard, each time a monster(s) your opponent controls is removed from play, Special Summon 1 "Eva Token" (Fiend-Type/DARK/Level 2/ATK 500/DEF 500).
Rulings
- This card's Summon does not start a chain, so "Thunder King Rai-Oh" can negate it.
- If "D.D. Crow" is chained to the ②, the Token is still Summoned.
