Haphazard Bombardment

Oracle Text

When Haphazard Bombardment enters the battlefield, choose four nonenchantment permanents you don't control and put an aim counter on each of them.

At the beginning of your end step, if two or more permanents you don't control have an aim counter on them, destroy one of those permanents at random.

Card Rulings

4/27/2018 The nonenchantment permanents that receive aim counters aren’t targeted. Permanents with hexproof can be given an aim counter this way.
4/27/2018 Aim counters are interchangeable. Your Haphazard Bombardment can destroy any permanent you don’t control with an aim counter on it no matter how that counter got there—for example, those aim counters may have come from a second Haphazard Bombardment that you or another opponent cast.
4/27/2018 Players can’t take actions between the time the permanent is randomly selected and the time it’s destroyed. Notably, if a land is randomly selected, it can’t be tapped for mana before being destroyed.
4/27/2018 If one or more of the permanents with aim counters on them have indestructible, select the permanent destroyed at random from among the permanents with aim counters that don’t have indestructible.
