If I have 2 Gemcraft Seers in play, do my units get Vision twice?

Ruling: Yes, with two Gemcraft Seers in play, every friendly unit has Vision Vision. Multiple instances of Vision trigger separately, so you perform Vision twice in a row when a unit enters play.

Sequence:

• Unit enters play
• First Vision trigger activates (look at top card)
• Second Vision trigger activates (look at top card again)

Nuances:

• Units can see themselves being played (Vision triggers when the unit with Vision enters play)
• This stacking behavior applies to other similar keywords like Shield (two Tarics would give units Shield 2)
