Update (Lorwyn Eclipsed):
With the release of Lorwyn Eclipsed, Simic Elf Tribal is getting an upgrade!
In: Champions of the Perfect , Out: Beast Whisperer
In: Chomping Changeling , Out: Shower of Arrows (bonus upgrade)
In: Sapling Nursery , Out: Bombadil’s Song
In: Castle Vantress , Out: Island (bonus upgrade)
Champions of the Perfect is a top tier card for every Elf Tribal. It is almost a strict upgrade to Beast Whisperer (which is already a great staple), but works only in Elf Tribal builds. A must-have card for our Simic Elf Tribal build!
Chomping Changeling is one of the best cards for every Tribal build as it combines artifact/enchantment removal on ETB with Tribal synergy. A must-have card for our Simic Elf Tribal build!
Shower of Arrows gets cut because it has similar utility with Chomping Changeling, but we prefer a body and Elf Tribal synergy over Scry 1.
Sapling Nursery is is a nice addition for every Landfall deck as it can quickly create an army of 3/4 green Treefolk creature tokens, while by paying 
and sacrificing it, it can protect them by giving them Indestructible until end of turn. A great pick for our Simic Elf Tribal.
Bombadil’s Song gets cut because we seem to be able to spare a protection spell in favor of a Landfall matters card. It is a great card for our build and a hard cut.
Castle Vantress is a Land with Scry synergy, as by paying 
we Scry 2. A great addition for our Simic Elf Tribal.
