Mirana

Big pull camp must not be blocked. You want to use it for pulling or gain extra farm by arrowing the big creep.

Make use of Mirana's long attack range to harass without aggroing too often.

Secure ranged creeps with Sacred Arrow if necessary.

Arrow catapults to prevent your buildings from taking extra damage.

Look around the map to save an ally in trouble with Moonlight Shadow.

Use Arrow to one shot hero controlled creeps. Especially useful against Chen, Enchantress, and Beastmaster.

Use the portals to roam around the map and set up kills with your lockdown.

Bring an Observer Ward to the lane to be able to see Mirana's Sacred Arrows.

Play around your creeps and use them as a shield against Mirana's Sacred Arrow.

Consider blocking the big pull camp. Mirana likes to farm the big neutral creep with Sacred Arrow.

Mirana roams a lot. Keep track of her movements and have teleport ready.

Pair Observer Wards and Sentries on map to see opponents approaching under Moonlight Shadow.

Carry detection on multiple heroes against Moonlight Shadow.
