Have the Llanowar Scout in play with the Retreat to Coralhelm. Play a land for turn, then tap Llanowar Scout to put Simic Growth Chamber onto the battlefield, let the Retreat to Coralhelm untap the Scout and put the land you just bounced into play. Repeat this with a second Simic Growth Chamber or other bounce land for lots of landfall triggers.

Saheeli's Pet Fish (using Saheeli, The Gifted).Deepglow Skate Buy + Mycosynth Lattice Buy + Saheeli Rai Buy
Saheeli Rai is a stand-in for Saheeli, The Gifted (C18, Mythic Rare).
Drop Saheeli 2.0 and Lattice first.
Then drop Deepglow Skate.
As long as she's at 4 or more loyalty and you haven't activated her yet,
she'll be able to use her ultimate on the spot.
Activate her Ult., and send the original to the command zone.
All new permanents will enter, with the token Saheeli being able to use her ult. again.
Creates infinite copies of all non-legendary permanents you control.
Flourishing Ballista ScalesWalking Ballista Buy + Rite of Passage Buy + Hardened Scales Buy
I realized a way to do it cheaper immediately following my last post with ballista.
Start with 3 counters on Ballista. Pull one counter off, target itself, it gets two counters back on it. As long as you resolve them in this manner (one at a time) it builds up to a creature with an arbitrary number of counters on it.
No drawChildren of Korlis Buy + Gift of Immortality Buy + Zur's Weirding Buy
With all three in play: prevent a player to draw with Zur's Weirding, at the end of his turn sac Children of Korlis and gain back every life you have lost. Return Children of Korlis in play with Gift of Immortality attached.
No one at the table can draw.
Infinite Quillspike + Infinite Snake TokensHapatra, Vizier of Poisons Buy + Quillspike Buy + Devoted Druid Buy
Have all three in play. Tap the druid for mana, put a -1/-1 counter on the druid to untap it creating a 1/1 snake token, use the mana to remove the -1/-1 counter with Quillspike. Repeat the process.
Synod Sanctum YasovaSynod Sanctum Buy + Yasova Dragonclaw Buy
This should be in here along with the different land yasova combos
Not so durable ServoDurable Handicraft Buy + Animation Module Buy + Ashnod's Altar Buy
So I think Durable Handicraft Buy and Animation Module Buy are a noteworthy synergy (for every 2 you spend every time a creature or +1/+1 counter comes int play under your control create a 2/2). But by adding Ashnod's Alter (or Krark-Clan Ironworks Buy) you get infinite come into play/leave play effects, which makes it a combo.
Don't rate originality as this has been done many times over with several different cards. But inexpensive and fun.
