first edition pikachu pokemon card Chinese Pikachu pokemon base set

A 4/4 with flying and haste when Klauth attacks, its controller produces an amount of mana in any combination of colors equal to the total power of creatures they attacked with that turn

Its all about pinging opponents around the table for damage, which isnt something you often get in a blue/white/black deck

When you do, you may cast target instant or sorcery card with mana value equal to the number of coin counters on this artifact from your graveyard without paying its mana cost

Fire Covenant also lets you pay life to remove creatures but functions more like a Toxic Deluge that doesnt hit your stuff and lets you pay any amount of life

The first two are part of a ten-card cycle that are maximized by a creature being at least two colors
