Chandra, Hopes Beacon Chandra, Hope's Beacon is yet another 6-cost Chandra that comes in at five mana
Heck, most of the picks we have here can be brought back by Sun Titan or a Sevinnes Reclamation, too
Pretty obviously if you don't have enough access to said colour you want to lay your land rather than cycle it and so for the most part these are just half the cost of the various other cycling lands and that makes them pretty all round great cards
