Focus on being everywhere at once on the map. Ivern has a surprisingly fast clear if done properly (sub 3 minutes) and has time for multiple ganks before scuttle crabs even spawn. Gank a lane, then use that prio/kill to get your team to support you on scuttle. If the enemy jungler is seen early at lvl 3, you can assume that one side of their jungle is not taken. Use ivern passive + smite to instantly take their most valuable camp.

Ivern's W provides vision, use this to check objectives. Ivern can bring a sweeper (since his W can act as temporary wards) and vision diff his way to objective priority. Use your W to hide yourself while getting scuttle crabs (Ivern's W no longer fully hides objectives such as dragon or baron. After youve gained vision advantage, a quick gank for prio/kill into team grouping for objectives is the optimal play. Place daisy in front of Baron while you are behind it in a bush and spam shields on daisy for the most healthy baron. Place daisy in rift herald pit and attack from a bush outside of the pit if you're on red-side for a safe herald (use your q to collect the eye).

Summon daisy and place bushes for your teammates to hide in. Target daisy on their backline, and either spam shields on daisy or a teammate who is being focused. Use your broken movement speed and ghost to kite the enemy and prioritize your own safety (if Ivern stays alive, he can pump out thousands of essential hitpoints through his E and Q, not to mention vision advantages with W). Protect your adc above all.
