Whats the cheapest and fastest way to make a tournament worthy Gladiator Beast deck?

Tournament worthy decks cost heaps man, for instance, a common staple card in tournaments is "Dimensional Prison", look on eBay, they cost like $70-$100 each. Possibly even more. I'm unsure if Glad Beast's have a structure deck, though im 90% sure they dont, so i would say buy structure decks like "Spellcasters Command" to get good staple cards for your deck, and then buy the Gladiator Beast cards off the net in a bundle. Then try out your prototype deck, and with a little bit more cash and research, buy cards that will improve your deck to a tournament standard, which would most likely be more staples... Anyway, good luck with your deck dude
