The name of the archetype comes from ursa (Latin for bear) and artic.
This archetype revolves around summoning Synchro Monsters based on the difference between the levels of the Tuner and non-Tuner monster, as opposed to the sum. All of the Main Deck monsters share the ability to summon themselves from the player's hand by tributing another monster:
During the Main Phase (Quick Effect): You can Tribute 1 other Level 7 or higher monster in your hand; Special Summon this card from your hand, also you cannot Special Summon monsters for the rest of this turn, except monsters that have a Level.
Each of the main deck monsters have an additional effect whenever they are Special Summoned. The level 7 non-Tuner monsters allow you to add an Ursartic monster from your deck to your hand, except themselves. The level 8 Tuner monsters have various effects to hinder your opponent, but require that you have another Ursartic monster on the field to activate it.
The archetype's Synchro monsters are not Synchro Summoned, and are instead special summoned from the Extra Deck by sending a Tuner Monster and non-Tuner monster to the graveyard whose difference in levels equals the level of the monster being summoned. Ursarctic Grand Chariot and Ursarctic Septentrion have the additional requirement that the non-Tuner monster is also a Synchro monster.
It is worth noting that the Ursartic Synchro monsters do not require Urasartic monsters to summon them.
This archetype is heavily reliant on tributing monsters, so cards that prevent tributing such as Mask of Restrict can be a major hindrance,
- The Synchro Monsters are summoned in a manner similarly to the anime exclusive mechanic of Dark Synchro Summoning, where the summoned monster's level is based on the difference between the Tuner and non-Tuner /monster's levels.
