This is the current list of counters I'm running in my Kess Reanimator/Control deck, and I feel I can squeeze in a few more modular counters. Would adding in Archmage's Charm and Drown in the Loch be fitting for the Control/Reanimator/Stax meta?

• 1x Force of Negation
  
• 1x Mental Misstep
  
• 1x Counterspell
  
• 1x Muddle the Mixture
  
• 1x Flusterstorm
  
• 1x Cryptic Command
  

*I have a small side of cards I board in for more competitive meta as in Stifle, Pyroblast and Red Elemental Blast
