Slash of Light is a two-mana monowhite instant spell that deals damage to a single creature equal to the number of creatures and equipment you have on your board
We'll also use the likes of Hitmonlee or Hitmonchan in combination with Sabrina and/or X Speed to knock out basic Pokemon where possible, as this not only nets us Prize Points, but allows us to then use the Pokemon Flute to bench the opponents discarded Pokemon again
As for what the Dragonite card actually does, its main attack deals a pretty impressive 250 damage - very solid for a basic Pokemon card, though your bench does take a hit
Picture is just for reference and each lot differs
Given that this card is yet again popping up on a bonus sheet, this time as a source material card, it's expected to continue being live only in formats such as Commander, Historic, and Modern as opposed to Standard or Brawl
