ART 1996 (1/1) Shichifukujin Dragon Original Art and Card at the MTG 10 years museum held in Grand Prix-Yokohama 23/24 August 2003
Having a card psa graded and rated in this system adds value, and is almost an expected etiquette when selling particularly old cards (like a charizard, a mewtwo, a blastoise or the legendarily rare pikachu illustrator card for example) that are high in value
The charge counters can come from any source
This actually came as a surprise to me, as conditional mana ramp that adds extra hoops to jump through beyond having fewer lands than your opponent is almost always unplayable, but when that hoop is take this creature off the battlefield, and the reward is both ramp and potentially filling your hand with any land with the Plains subtype, the results are surprisingly effective
You can fill your hand back up too, being in green and having a Commander that draws cards
