Castle Garenbrig and Nykthos, Shrine to Nyx are excellent mana ramp lands thatll let you pump out creatures early and keep that pace up as you keep drawing cards
All right, that was a lot of fun
Past in Flames gives you the opportunity to bring them all back, provided you have enough mana
Recently desparked, Saheeli finds herself on Ixalan, lending her skills with artifacts and automatons to build replicas of some of the most powerful creatures on the plane
My preference is MTGprint.net, though they dont allow you to upload custom designs
Im still skeptical of spacecraft and station in general, but lands decks can put a lot of power in play, so turning Hearthhull online should be easy
