"Is it?" he replies gently, looking over the size of the tree in general and then down towards where Strange has started his enchantment. He activates his power to choose and begins to ascend into the air. About halfway up he'll slide his arm right through it and severe the tree where it stands. It splits from the base and he'll grab onto a branch to try to sustain it so it doesn't land on Strange itself. Only when it hits the ground with a heavy thud will he size it up.

There is now a base of the tree stuck in the ground and the other upper half is now settled against it, "That should cut it down to size." He looks up at Strange's question when he lowers himself back down to the ground, grabbing branches as he goes to ensure it doesn't tip over right away, "I could give it a push but then the water might rise for a moment." That is if the reflection didn't work how he was considering it would.
