Ascend lets us just pump Mana Geyser or other effects into this, and for the same cost, get back as many creatures as we like
@pokemonrevolution recently presented a new and likely theory for these Grey Thick stamps, which I will quote here: Grey Stamp Theory Grey stamped 1st Edition Base set cards for the most part have commonly been considered to exist because of either A) The ink was low when they were stamped B) The stamp was not pressed down with enough force to create a nice dark color
LINK - 2 Normal Deck 9.2 6 [28311] JP069 Branded in High Spirits Quick-Play Spell Reveal 1 monster in your hand and send 1 Level 8 Fusion Monster from your Extra Deck to the GY with the same Type that has 2500 ATK or DEF, then you can apply this effect
Its removal is fairly efficient (see Lightning Bolt), but it doesnt scale well into the game as creatures and boards get larger
Their last card in the Spell/Trap department is [Fraud Freeze], a Continuous Trap that immediately bounces back a monster to your opponents hand, but with some limitations holding it back from being seriously considered - it only bounces back all monsters your opponent controls if they Special Summon a monster from their hand (outside of the Damage Step), and it destroys itself if you dont control any Flower Cardian Synchro monster
