<small><small><small><small>Quarantine Field raises the cost of Creatures and Supports. Also there is direct damage. Creature Token spells are one answer, or [[:Category:Summon creatures|Planeswalkers that Summon creatures]], or [[:Category:Damage opponent|PWs that do direct damage]] like [[Ral, Izzet Viceroy]], [[Narset of the Ancient Way]] or [[Kaya, Orzhov Usurper]] or make the opponent lose life like [[Kaya, the Inexorable]]. All its creatures are tokens, eg Nissa's Renewal and Part the Waterveil combo, except for the creatures it steals with Exert Influence. Play with Mana conversion of your PW's colors, and the Sow Oblivion loyalty ability will give Oblivion Sower enough loyalty to activate it every turn. Unless your PW is Black, in which case the AI may decide against it.</small></small></small></small>
