Ojama Deck

The Ojama deck obviously uses the Ojama series of cards. There are many defining characteristics of the Ojamas: their low level and the fact that the first three (Yellow, Black, and Green) are all normal type; their ability to make opponent's monster spaces unusable: and the fact that all have 0 attack, but some have quite high defense. Listed below are cards to take advantage of these characteristics:
 * Low level, normal type: This makes the original Ojamas searchable by cards such as The League of Uniform Nomenclature (which as a dead giveaway has the three Ojama Yellows shown in the card art), Human-Wave Tactics, and Enchanting Fitting Room.
 * Monster Space Lockdown: Ojama King, Ojama Knight, and Ojama Trio all have the ability to make opponent monster spaces unusable. This can lead to an effective lockdown, particularly when combined with other cards that lock monster zones, like Ground Collapse, and to a lesser extent Narrow Pass and Spatial Collapse.
 * High defense: This can be combined with the Zone lockdown to produce practically an OTK. Fill up opponent monster spaces with Ojama Tokens and Ground Collapse. Summon Ojama King, and ideally two other Ojamas. Then, switch the Attack and Defense of all monsters with either Shield and Sword or the Ojama's own field card, Ojama Country; this raises the King's attack to 3000. Finally, use Ojamuscle, destroying the three Ojama Tokens on your opponent's side of the field and a number of Ojamas on your side of the field, thus raising Ojama King's attack to at least 6000. Attack directly, hopefully to win.
