With mtg plugin loaded i try to search using lackey search filters
Using the following steps
1: txt filter = not containing "Ante" (old MTG term) but it also filters anything that has the letters "ant"
EG: overwhelming Splendor
overwhelming Splendor mtg card txt
enchant player. the issue is lackey sees the ant and filters it out
Overwhelming Splendor's text also contains the word "enchanted", which includes "ante". If you want to remove all cards that reference ante, try excluding "ante.", since they all have that sentence about removing them from your deck.
