As infinite as possible given finite life totals. Ah, my favorite combo ever.

@Background Pony #E6C0  
Renegade Lovebug: Nope. Lifelink only applies to damage, and not all life loss is damage. (And thanks to infect, not all damage is life loss.) The rogue changeling doesn’t go infinite until you throw in Exquisite Blood
 
Push Past the Pain: Perhaps, but “that which kills you makes you stronger” seems like a great fit for dragons.
 
Moonclutch Tree was inspired by young Granny’s bedtime story to her trees. Feuding Bear is based on Goldie Delicious’s misreading and a dash of Burnt Oak’s obvious Sam Elliott-ness for the flavor text. Four-Season Promenade is based on the bit of the musical number where the lovebirds walk together from summer to spring.

Good representation of the scene. It’s interesting to note that symmetrical land destruction effects have reduced impact on Red decks themselves, given their fast mana. I’m not sure if that would effect costing though.  
Regarding the other cards from the post:
 
Ponyville Trumpeters: Any creature including themselves, instead of just legendary? Interesting choice.
 
Renegade Lovebug: Don’t those two abilities go infinite together?
 
Push Past the Pain: I’d have thought Persist would fit the flavor better.
 
Confluence of Champions: Great against Derevi, Empyrial Tactician. Combo nicely with Crimson Honor Guard.
 
Emblazoned Banner: I like the mechanical space of this one. Too bad we won’t get to see it officially given they don’t make cards with the Tribal type anymore.
 
On the (slightly) older cards:
 
Unceasing Admirers: I like how it’s a Lieutenant without an all upside ability, and forces you to think about when you should play your commander.
 
Slip Under the Floorboards: I like the bottom of the deck bit. Good mechanical expression of flavor.
 
Cold Feud: I want to use this in a draw mill deck.
 
Overflowing Lore: Combine it with Laboratory Maniac or Tamiyo, Moon Sages’ ultimate, and laugh at your opponents despair.
 
Moonclutch Tree, Feuding Bear, Four-Season Promenade: What inspired these ones?

@FanOfMostEverything  
That’s fair.

@The Hittite  
No, actually. And please don’t elaborate.

I don’t suppose you’ve seen the leaks from Ixalan?

You know, for such a peaceful show, we sure do end up with a lot of land destruction type cards out of it. Or at least, scenes that would potentially make for good land destruction type cards. If it’s not the threat of a changeling/dragon war, it’s Celestia’s nightmare form, or time travel run amok, or any other of the end of the world as we know it type stuff that happens once a week like clockwork.

Nice.
