Note that these requirements are for the Pokmon TCG specifically
But if we're looking at great artifacts that draw cards, Sword of Fire and Ice is amazing in its Jack-of-all-trades-ness: Even expendable fodder turns into a must-kill threat when wielding this fiery blade
Devastator's hydra typing makes it a mainstay in Gargos, Vicious Watcher decks, though being green is usually reason enough to slot it into ramp-based strategies
Grave Upheaval then is not just a recursion spell for the best creature in all graveyards, but a great spell that can keep your land drops on curve in a pinch
