Quote from JustSeph1 »Is Kambal good vs. control? I see a lot of people running 2 of him, but I'm not totally sold on him.
He is a must answer threat. They can’t let him hit the battlefield without losing life. If they counter him then hopefully you can follow up by resolving a Reveler or Liliana.
If they don’t have a path or bolt to kill him then they are forced to take a ton of damage while they opt, visions, etc or counter other threats. He forces them to make suboptimal plays and increases your threat density.
He can also chip away for a couple points of damage here and there and can fight off opposing snapcasters.
So while he isn’t the best card in the matchup he is a good one. Though he is primarily a silver bullet card for storm and burn.
