I guess the first hurdle is ensuring that the samara tree/druid has enough vine markers to spread the seed pods around.  I guess packing a vinewhip staff and/or a vine tree too would be pretty important in such a build.

I've played a couple of games now as the druid and unless I am missing something terribly (which is likely) I find the seedling pods to be a great addition to an already versatile mage.

Using Tatatree speeds up the process of getting 3 mana on them and typically I am doing so much more to get the opponent's attention that they ignore the pods until they are popping with death!!

I've also used them to great effect as bait....either my opponent has to come within range to attack them, placing themselves in an ideal zone for me to bring the pain or let them just build and build!!

Also between two Necromancers it doesn't take long until you have such a massive army that they have better things to worry about than the Idol of Pestilence/Deathlock combo you put up in the back corner.

Much needed buffer between slinger and Grimson. Solid.
