Does Blue Teemo's ability damage work with Void Gate? If he reveals 5 hidden cards, does his ability deal 10 damage on this battlefield?

Ruling: Blue Teemo's ability is a single instance of variable damage (X damage, where X is the number of Hidden cards revealed). Void Gate adds +1 to that single instance, so revealing 5 Hidden cards would deal 6 damage total, not 10.

Nuances:

• The ability only triggers deflect once, not once per revealed card, confirming it's a single damage instance
• An older ruling suggested it worked differently (adding +1 per card revealed), but this was explicitly changed
• The card's wording could be interpreted either way, but the official ruling treats it as one variable damage instance
