vs Delver/Aggro
out- 4prime titans, 4frost titans
in- 4 metamorphs, 1acidic slime, 1thrun, 2crushing vines
[thruns>prime titans vs everything in delver (except phantasmal image) and, and can't be countered + better in general vs aggro, GSZ's fetch up more strangleroots, elders and thruns, metamorphs to deal with geist of saint traft on turn 3]
vs Ramp
out- 4strangleroots, 4elders, 1thrun
in- 4tracker's instincts, 1BS colossus, 1increasing savagery, 2metamorphs, 1acidic slime
[tracker's instincts make sure you always have threats and strangleroots can't really race a ramp deck on their own anyways and area dead draw later, same for elders and thruns, acidic slimes can take out inkmoth nexi and provide good GSZ targets and titan blockers, savagery is a threat they can't really answer which flashes back for more value, metamorphs can copy a turn 3 huntmaster or turn 4 titan, or kill a thrun or elesh norn (if it's that variant)--- out control the control deck]
vs Control
out- 3prime titans,
in- 1predator ooze, 1blightsteel colossus, 1thrun,
NOTE: ~4phantasmal image maindeck instead of strangleroot geist? cut down on GSZ's and adjust the manabase--- if geist turns out not to play an effective role in the deck, maybe phantasmal image will? in that case, replace dungrove elder as well (since there will be fewer forests)
