Easy 3 star with hogs because there's only 2 double giant bomb possible locations. The top one would be triggered by the golem + heros journey to take out the defensive queen. To easily trigger the bottom dgb, the attacker would only have to drop 2-3 balloons on the archer tower in front of the double giant bombs, then drop a single hog to trigger both bombs. The attacker then has 3 heal spells and 30ish hogs for a base with zero giant bombs, an obvious 3 star.
Impecable DGB placement and air defense placement. The only thing I would worry about with this base is GoWiPe/GoWiWi. I would love to see how this base would do against those types of attacks! 5/5 from me!
