You can use the ability the turn Nebula arrives because it doesn't have exhaust as part of the cost. — Sirlin
As a conceptual shorthand, think about flying and anti-air as follows: Ground forces without anti-air can only shoot straight. They can never hit fliers, ever. Flying forces can shoot both straight and down. Anti-air forces can shoot both straight and up. This is never a handicap because even though they CAN hit patrolling fliers, they aren't forced to. As a patroller, you only stop an attacker if it's on the *same* level as you. Anti-air ground forces on patrol will shoot at fliers as they fly over. — SirlinFliers can ignore patrollers that don't have flying. In other words, they can attack something else instead if you want. — SirlinFliers cannot ignore flying patrollers. The usual rules of the patrol zone apply, meaning if you want to attack with a flier at all, that flier CAN attack patrolling fliers so it must do that rather than attack other things such as non-patrollers or tech buildings. — SirlinWhen a flier attacks another flier or gets attacked by another flier, they both deal combat damage to each other as usual. When a flier attacks a ground unit or hero without anti-air, the flier deals its combat damage to the ground thing and the ground thing does NOT deal any combat damage to the flier. Ground forces without anti-air cannot even attack a flier at all. Ground forces with anti-air can attack fliers and deal combat damage to them as usual when they do. — Sirlin
Resist X Rulings
This has nothing to do with attacking. Opponents don't have to pay to attack something with resist, they only have to pay to target it with spells or abilities. — SirlinThis does stack, so if one of your units gets resist 1 twice, opponents must pay 2 gold to target it with spells or abilities. — Sirlin
"Sneaking past" means you can ignore patrollers when attacking and attack anything you want. You can also attack the patrollers if you prefer. — SirlinWhen something invisible attacks an enemy unit or hero, that enemy unit or hero DOES deal its combat damage back as usual. — SirlinIf an opponent has the Tower add-on and their tower has already used its once-per-turn detect on something, then you attack with something invisible, the Tower will not deal its damage to your invisible thing. It would if it's once-per-turn detect hadn't been used, but it can only damage things it can see. — SirlinYou can [target] your own invisible things whether you have a detector or not. — Sirlin
