Does Siphon Power target, and can you skip the -1 might to enemies part of the effect?

Ruling: Siphon Power does not target units (it targets the battleground). You cannot skip parts of the effect, so you must give opponents -1 might.

Nuances:

  • The ability targets the battleground itself, not the units, so it bypasses deflect
  • You cannot choose to skip giving -1 might to avoid paying deflect costs since the ability doesn't target units anyway
