Text (CF): 2/2, First Strike. ; {W}{U}{B}{R}{G}: Until end of turn, ~this~ becomes a Dragon, gets +5/+3, and gains flying and trample.
While it is a Dragon, it is not a Human Knight. [Conflux FAQ 2008/12/16]
You can play the ability more than once. The second time it likely won't have any effect other than to give it an additional +5/+3. [Conflux FAQ 2008/12/16]
Gaining flying after blockers are declared won't cause any of those blocks to become illegal. [Conflux FAQ 2008/12/16]
