Perpetual Growth/ Endless Ramp
A themed casual deck with swallow splashed in.
I suppose I should justify including 3 copies of chrysalis. Being a 0-cost card you can do some pretty cheeky things with it. If your opponent is pressuring your tree or orb you can easily surround it with chrysalis. It can also be used offensively as a cheap (yet clunky) teleport by activating it immediately as if the creature was just summoned there. Finally, it can just be used to slowly buff any creature, preferably not a seedling or wisp as these creatures already buff themselves, but a kodama, elemental, one of your injured big dudes, or even Shozen. Although doing this has a severe downside: it essentially removes one of your creatures from the game for the number of turns allotted. Use with caution.
