pokemon sword and shield cards charizard V (153/172) [Sword & Shield: Brilliant Stars] Fire Inferno X (90x) Discard any amount of Fire Energy from among your Pokemon Pokémon TCG: Sword & Shield:

The deck has a modest set of point interactions, between removals and counterspells (Imprisoned in the Moon, Hanged Executioner, Arcane Denial, Crush Contraband, Swords to Plowshares and Darksteel Mutation) plus three sweepers, (Fell the Mighty, Flood of Tears, Kirtar's Wrath)

The change in power level between four and five drops may not be the steepest change but it is one of the more significant ones as it falls within the realms of the cards you can include without ruining your curve or consistency
