Early Game
Scuttlecrab, Sejuani, Rakan, and Vi are all cheap frontline bodies from the start. Play a normal econ opening while banking toward level 6.
Mid Game
Hold at level 6 and slow roll for Caitlyn copies. Sivir is a secondary carry option until Ashe is upgraded, and Tristana fits the Hunter trait without needing dedicated items.
Late Game and Final Board
A three-star Caitlyn with attack speed items is a reliable, easy-to-execute win condition, and Ashe adds a second damage source once you push to your final levels.
Best Items
Guinsoo's Rageblade paired with Kraken's Fury is Caitlyn's core; Ashe wants Last Whisper and Spear of Shojin.
Best Augments
Backup Bows and Building an Army suit the early roll-down; Ascension II and Heroic Grab Bag support the mid game; Baron's Lair and Golden Ticket close it out.
Positioning
Scuttlecrab, Sejuani, Rakan, and Vi wall the front. If Scuttlecrab is contested, make Sejuani your main tank instead, and pass leftover tank items to her.
Flex Units and Alternative Carries
Sivir and Tristana are the flexible utility slots depending on your lobby.
Strengths and Weaknesses
One of the easiest comps in the format to pilot, with a reliable floor. Its lower cost ceiling means it's a safer top-four plan more than a guaranteed first place against stronger five-cost boards.
