protective sleeves for pokemon cards Ultra PRO: Pokemon: Deck Protector Sleeves: Energy: Metal Type (65ct) x 3.5 in Ultra PRO Pokémon - Energy

Raffine is unique from other Sphinxes in that it rewards you for going wide, however, you really only need two or three successful attackers for the connive triggers to quickly get out of hand

HCD Solid Color seems like a reasonable budget sleeve, but I can't recommend buying them because several came out of the package unusable

The Thunder Junction Limited format has entire archetypes built around this concept, from decks that care about casting two spells in one turn to decks that reward you for not casting any spells from your hand at all

You can expect roughly one 1/1 and +3/+3 from its trigger each combat while it provides more cards to fuel your attacks
