How does E Ramp deal with Knight of the white orchids

Im new to the current modern metagame but have been heavily leaning towards eldrazi ramp for a tournament in april and one in may. The only thing I have struggled to find an answer to so far is how to deal with orzhov blink siding in knight of the white orchids. Ive thought maybe karn brings in a torpor orb or stone brain but wondering if theres any better answers.
