Sidewinder Naga

As long as you control a Desert or there is a Desert card in your graveyard, Sidewinder Naga gets +1/+0 and has trample.

Hour of Devastation

If an ability checks whether you control a Desert or there is a Desert card in your graveyard, having more than one doesn’t matter. Controlling one is the same as controlling five. There is also no extra bonus for both controlling one and having one in your graveyard.
