T1 Land, Explorer

Crop Rotation also works in this opening because you go
T1 Land, Explorer
T2 Land, Crop Rotation, get Tower, sac Explorer.

Alternatively, you can go
T1 Land, GSZ for Dryad Arbor
T2 Tower (or Rotation into Tower)

This generates 1BBG on T2.
Gotcha ... wait, Crop Rotation is a viable option now? . . . that's actually pretty good with Rallier.

T1 G Source, Vet
T2 P.Tower-->Vet Trigger-->G Source and W Source (GGBBW Available)-->Crop Rotation (P.Tower-->V.Stronghold)-->Rallier (P.Tower)

Five mana if you need a X = 2 Deed, or the Two Towers synergy assembled.
