The Pokmon TCG revolves around an active Pokmon and its attacks, each one needing energies
Cube decks have less redundancy and so getting the dream of turn one Lackey into a Siege Gang has incredibly low odds
Creatures (31) 3 Goblin Vandal 4 Goblin Recruiter 4 Goblin Matron 4 Goblin Lackey 2 Kiki-Jiki, Mirror Breaker 3 Goblin Warchief 1 Goblin Sharpshooter 4 Goblin Piledriver 1 Gempalm Incinerator 1 Siege-Gang Commander 3 Goblin Ringleader 1 Skirk Prospector Lands (18) Spells (11) Sideboard Once you stack your deck, every Ringleader will hit four more Goblins, meaning you can basically just draw whatever sixteen Goblins you want (and thats not even factoring in Goblin Matron)
Uh, okay then, Hydro-Man, Fluid Felon, sure
If you can answer the creature, the life you got because they werent attacking you can give you some more time
Summary Pick favorite lands to give deck synergy, consider theme options like full-art or promo lands
