Hi All, can some one help me figure out this interaction

Had a game with Wildbonder + Reptilian Reflection.

Cycling to make it a creature did not allow me to perform *super* trample.

Attached a picture - the reptilian reflection not shown - but you can see the increase button greyed outAnd the wildbonder on board

Increase arrow Greyed out - Reflection in under the card**

Edit - further screen captures against SPARKY

Pre - Combat

Assign Blockers - no option to over trample

Assign Damage to blockers + normal trample
