Slam BB early, make sure Irelia and Vex aren't contested. No one rerolls Morg, so even if some play black rose units you should be fine. Roll to 33 gold after Krugs, then stabilize and slow roll at 5. Always worth doing because of shop odds, but becomes incredibly strong with high gold pve rounds.
Never itemize renata, play heimer or malz if you find them early. If you hit vex 3 and irelia 3 early, push levels and move morg items to malz or heimer. Morg and Vex are worth playing late, especially with augments like No Scout No Pivot and Scoreboard Scrapper. Tank Anomalies are best. Prio Shred mid game, and make sure to get antiheal, this comp has no burst. DO NOT PUT ANTIHEAL OR GUNBLADE ON MORGANA, THIS CHAMP DOES NO DAMAGE LATE WITHOUT AP.
