That ability, Cursed Blast, is absolutely disgusting
Some cards will make you a 'lil bit safer, like Sliver Hivelord, Darkheart Sliver + Hibernation Sliver, Sedge Sliver or Crypt Sliver, Diffusion Sliver, Ward Sliver, Root Sliver, Frenetic Sliver (in last case scenarios) , Crystalline Sliver, Pulmonic Sliver, Asceticism, Privileged Position and Steely Resolve
This invalidates every Esper control general before it, and conveniently drops a turn AFTER Counterbalance-plus, it's almost a better Sensei's Divining Top
Ruin Crab
Either way, Im looking forward to seeing how many of these MTG Sliver cards get the premium treatment
In case your commander isnt on the battlefield yet, you have Fate Unraveler and Underworld Dreams to keep pressuring whenever your opponents draw cards
