U.A.

"U.A.", short for "Ultra Athletes", is one of two TCG exclusive archetypes that debuted in Duelist Alliance, the other being the "Burning Abyss" archetype. Currently, the members are EARTH Warrior-Type monsters that resemble athletes wearing cybernetic armor.

Design
The archetype is based on positions played in various popular team sports, with every set including monsters hailing from a different sport. The Spell Cards represent various aspects of sports, such as location ("U.A. Stadium"), uniforms ("U.A. Powered Jersey"), techniques ("U.A. Turnover Tactics"), team contracts ("U.A. Signing Deal"), or penalties ("U.A. Penalty Box") all of which are related to the unique sport of the accompanying "U.A." monsters in the set they were each released in.

Playing style
All "U.A." monsters share the same effect of Special Summon themselves by returning a different "U.A." monster from the field to the hand. The Field Spell "U.A. Stadium" can search an "U.A." monster when another one is Normal Summoned, and gives a permanent ATK boost of 500 to all your monsters ("U.A." monsters or not) when you Special Summon an "U.A." monster for the first time during any turn, once per turn.

The basic strategy is to Normal Summon "U.A. Midfielder" each turn, allowing you to add "U.A." monsters to your hand via the effect of "U.A. Stadium". Summon aggressive monsters like "U.A. Mighty Slugger" and "U.A. Playmaker" during your Main Phase 1, attack using the protection that "Slugger" grants, then swap your monsters out during the Main Phase 2 for protective monsters like "U.A. Goalkeeper" and "U.A. Perfect Ace". In the event that you don't have an ideal set-up of "U.A. Stadium" and "U.A. Midfielder", Tribute Summons can be facilitated with "Heroic Challenger", "Hieratic", or "Burning Abyss" monsters, to name a few, as well as "The Monarchs Stormforth", "Feast of the Wild LV5", etc.

Weaknesses
The U.A. archetype is extremely reliant on its first Normal Summon; effects that remove the Normal Summoned monster from the field can essentially end a "U.A." player's turn, if they control no other monsters. Likewise, cards that prohibit Special Summoning are extremely effective.

Due to the amazing amount of searches it gives, destroying "U.A. Stadium" also deals a critical blow to this Deck.
