Combos Utilizing Fyndhorn-Elder

play the elves and the alarm then the guardian, produce infinite 1/1 saprolings that you can sac to make all saprolings infinitely huge

Use the elder to produce the mana, so the queen can make a creatur, so the alarm can untap all the creatures, and then repeat as many times as you like.

Use the Elder and other elves to pump up a huge howl from beyond. Then sacrifice them to the angel. Toss on a giant growth or two if you have them. Boom.

have the symbiote, hivemaster, and elder in play. tap the elder to put the herald into play, use the symbiote to return the herald and untap the elder. put an insect token into play. and repeat

Attach Freed from the Real to Fyndhorn Elder and tap for two green mana. Use Orochi Leafcaller to get an island, untap Fyndhorn Elder and boom, you now have one extra mana that can be changed to any color of your choice. Infinite mana.

I have this small theme with a combo of black land destruction cards (choking sands, despoil, rain of tears) and assassinate, and it works well.
