Hmm, well, I think anyone with multi-hits that has a chance to remove or steal buffs would be a good replacement. Mons that come to mind:
• Wrath
• Purple Droid (has Void Shield aoe and multihits)
• Alliance General (on Counterstrike)
• Sentinel Allied Soldier
• Gunner Golden Son (On Purge)
• Lady Azov
• Mayan Priestess Sentinel (on Counter)
• Assassin Trickster (Immortal or Double Fate)
• Warrior Trickster (on Counter)
• Gunner Hellraiser (on Purge)
Also, I suppose any multi-hitter that can use the Purge Talismans has a chance to be useful as a replacement. Also any team or mon that can make use of Echo buffs, like maybe a team with the Crimson Pharaoh Dog and buff removers can work. Haven't tried it though.
