This is great, as Warren Warleader can build a good board the turn it comes down, plus you dont need to ever attack with the 1/1 offspring either
What affects the value of Garchomp
Decks With This Card Recent public and tournament decks using Chaos Ruler, the Chaotic Magical Dragon
For example, a copy of Gaea's Cradle from Urza's Saga (the legal version) costs north of $800
Not only do topping Decks suffer, weaker Decks like Heraldics (at best they get a 2000 beatstick who is a RotA when he dies) and Scraps (can peak at 2500, but usually will hit 1900 instead, and the Synchro Monsters are one of the biggest parts of making the Deck work)
Combined with cards like Thopter Assembly or Sai, Master Thopterist, its easy to go infinite or just take a bunch of turns in a row
