I was working on something when Worth Wollpert, an R&D member from back in the day, called my name
Vennominaga the Deity of Poisonous Snakes Red-Eyes Dark Dragoon Lunalight Liger Dancer Expurrely Noir Ancient Gear Howitzer (weak stats, but unaffected by other effects) Black Luster Soldier Soldier of Chaos The Arrival Cyberse @Ignister Raidraptor Untimate Falcon Cyberdark End Dragon The above list not exhaustive, and some of the cards listed may not be considered true towers, but they are all monsters that pose a unique challenge for removal and offer some form of an unaffected effect that makes these cards very powerful and difficult to work around.
