Mcginnish the JUNGLE DESTROYER (Echo Shard)

Focus push and farm in lane. As soon as jungle camps spawn use turrets to take. After 10 minutes max ult and use it to help you farm all t3 camps early. Bounce between lanes and jungle and just farm all camps. Even when you've lost lane you'll get ahead easily by taking t3 camps with your ult. BECAREFUL. You'll be carrying a LOT of unsecured souls, do not take aggressive fights before dying. Focus on defending your own towers, pushing waves out, and farming jungle until you hit power spikes, then fight with team. Heal scales with spirit and is extremely good in team fight.
You can set up for mid extremely easily. Put down turrets in the corners of mid pit, once 4 down start putting them on high ledges while team finishes mid boss.
