Heh. Injecting a bit of humour there, with Teleport. That is a rather long list of cards to read through, after all. ; )
The problems I see with Samara Tree are myriad: it requires a prohibitive investment in mana for the rather minor benefits it provides; the much-better Vine Tree can cast the Seedling Pods as well; you rarely if ever have enough mana to make both trees truly useful; since they're Conjurations, more than one Pod can't be stacked in the same zone at the same time; it telegraphs to the opponent that Something Bad Is Coming In That Zone; and you rarely want to use more than 2-4 Seedling Pods in a typical game anyway (making the Cantrip aspect irrelevant).
