Hidegetsu

[Noblellama]

If I use {Heartless Hidetsugu}'a ability and while it is on the stack I {Twiddle} him and do it again, where does that put my opponents who were all at 40?

[Ekann1]

40/2 = 20
20/2 = 10 life.

It only checks their life total as the ability starts to resolve.

You talk about opponents. But it hurts you too, right? As the caster of that spell.

Yes, heartless Hidetsugu's activated ability hits each player, including yourself.

[Gorzo]

I'm less concerned about my own life total when HH is wearing a {Batterskull}...

He is pretty hilarious with lifelink

Also, if you can convince people to bring your life total below 20 in a game of EDH... {Tainted Strike}!

What's a good {R}{B}{G} commander for my hidegetsu/infect/melira deck?

I'd say {Prossh Skyraider of Kher} because if you give him infect you just win

[Mytra]

My favorite: Heartless Hidetsugu & Dictate of the Twin Gods.

Then is the question, are your lifepoints odd or even.

If you want to blow everyone's mind and get confused looks, use {Xira Arien}.

If you want to be heartless, cruel, and nasty, use {Shattergang Brothers}
