The Main Deck Negators are Endymion, the Mighty Master of Magic (S/T card or effect, SOPT), Mythical Beast Jackal King (monster effect, SOPT), Reflection of Endymion (bounce when SS by Selene), and, in Draw Endymion, Magician's Right hand (first Spell Card/effect each turn)
Features*: Easily search cards by specifying Card Name, Card Text, Link Markers, etc., and even use your camera to access the card recognition function to easily search for cards
The ultimate edition is absolutely the best place to get in to Mage Knight if you don't already have it, and it's also the best place to get all of the expansion content if you already have the base game but don't have the expansions yet, especially considering the price that each expansion is currently going for
Snap on, remove, any time you like
During the End Phase, destroy all monsters that were affected by this effect.
I highly recommend using the Dueling Nexus deck builder as it's by far the best one
