Bumba's Hammer if opponent team consist of mostly one shots, relic go either aegis or beads both pre safe I prefer aegis because you can use your ult to get away if needed, blink if you want to play aggressive.
If their team contains a bunch of one shot characters hammer is much better than spear because autoing into a one shot character is very risky.
if their team is not so tanky upgraded blink is an amazing choice.
If you don't want the sustain Arondight for chase down.
