Fast answer
For Horde Invasion, build around Dewgrub, Buddi, and Voltfawn, then add a fourth slot that fixes your weakest lane.
What the mode asks from you
This mode is less about one perfect burst window and more about surviving repeated pressure without your board unraveling.
Best Tatari for the mode
- Dewgrub for steady wave pressure
- Buddi for sustain and board stability
- Voltfawn for control and carry damage
- Goonbug when waves start crowding your front lanes
- Frugling when you need more splash coverage
Good mode habits
- stabilize weak lanes before overcommitting to damage
- save your strongest evolved line for the lane that fails most often
- value slow, control, and healing more than you would in a short boss fight
When a run falls apart
Most bad runs fail because:
- the team is too greedy
- the board lacks support
- one lane gets repeatedly ignored
The upgrade priority inside the mode
If your Horde team already has damage, the next best investment is often survival or control, not even more damage.
