Since Charizard is more common than Charizard Ex, it serves well as a placeholder until you can acquire the more powerful version
It gives a stats bonus when it attacks, which on its own is good, but I dont ever see this being a prominent commander
A constantly respawning hellspawn that gives you free fusion material, 2 free synchro levels(Sometimes 4), and free rank 2 and 4 xyz at nearly no cost
The cards in excellent condition command a premium, with lightly played (LP) jumping to almost $15 and near-mint (NM) at the top, selling for roughly $23
In 1999 alone, starting in February, six booster packs made up of between 40 and 52 cards were released, slowly introducing the many card types that have become standard in the game today
