MTG >Combos >ナレッジプール +塔の長官、ボロミア +

The combo involves having both

ナレッジプール

and

塔の番人ボロミア

on the battlefield. This results in your opponents being unable to cast spells from their hand or spells exiled by the Knowledge Pool. The combo functions by utilizing Boromir's ability to prevent opponents from casting spells from their hand and combining it with the effect of Knowledge Pool to exile any spells opponents try to cast, effectively locking them out of playing spells.
