pikachu jumbo pokemon card - Oversize/Jumbo - SWSH061 Lightning Disconnect (150) During your opponents next turn Pikachu V SWSH198 Ultra Rare

If its your turn, you can nab the best board for the turn and do some real damage

Is it from a popular set/does it feature a popular Pokmon

Similarly, Oldschool 93/94 + Artifacts = Robots

Honorable Mentions The Odyssey Eggs The original Odyssey Eggs dont fit my description of giving you a card back, although they fit colorless mana into specific colored mana like the signets

Repeatable ramping for just two mana (plus three life!) is not to be underestimated
