This has been denied in the past, its called overpowered mode for a reason because epearls in a skygame are OP thats why i dont think epearls will be added to the other two modes but heres a list of things you can try
1. Tunneling- safebridge with a roof
2. Safebridge- walling up the sides of the bridge so you cant be punched off
3. Wide Bridge- making bridges 4 or higher blocks wide
4.Long Bridge- only working on maps where islands are far apart (like aztec or space) this is building way out beyond render distance and ambushing from behind
5. Staircasing: simply making a large staircase up this shields you from getting shot as long as you dont have to build more platforms for the stairs
6. Skybridge: building a bridge high up inthe air
7. Shielding- as long as you arentt spleefed, your shield dosent break, you get attacked from behind, or the bridge is broken you can just death charge your way across
8. Kill Spree- killing the entire enemy team (with the power bow or the void) then skybridging beyond their reach
9. Low baller: this a bridde at the very bottom of the map
