Virus kills itself?

[Solis]

Question in regards to the Virus card

Virus (R) (YC)
ST:10 HP:10 G:0 + Yellow
Land Limit: xGreen
Item Limit: xWeapon xArmor xScroll
Boost (all creatures HP-10)

Creatures never boost themselves, right?

So merely entering into battle with this guy won't kill itself, will it?

That is correct - Virus will not kill itself. If you have TWO virii on the board however, that's a different story...
