Ursarctic Quint Charge

Once per turn: You can pay 700 LP, then activate 1 of the following effects;
• Add 1 "Ursarctic" monster from your GY to your hand.
• Tribute 2 "Ursarctic" monsters (even if face-down), and if you do, Special Summon from your Extra Deck, 1 "Ursarctic" monster with a Level equal to the difference in Levels of those monsters, ignoring its Summoning conditions.
When your "Ursarctic" Synchro Monster is destroyed by an opponent's attack: You can activate this effect; your opponent must shuffle cards into the Deck so the total number of cards in their hand, field, and GY is 7.
