I have a two questions about Ordinary Pony to make sure I understand the errata (...target non-Horse creature you control that wasn't put onto the battlefield with this ability this turn...)
Scenario 1)
I have Kiki-Jiki, Mirror Breaker and Ordinary Pony in play. I activate Kiki-Jiki to make a Pony token. The pony blinks Kiki-Jiki. Kiki-Jiki makes another Pony. Since that pony is different than the one that blinked Kiki-Jiki before, I can target Kiki-Jiki again and repeat this to make as many ponies as I'd like. Is that correct?
Scenario 2)
I have Purphoros, God of the Forge and Restoration Angel in play. I cast Ordinary Pony and choose to blink Restoration Angel. With Restoration Angel, I blink Pony. Since the game views the pony as a different creature than the one that brought Restoration Angel into play, can I repeat this process until Purphoros kills my opponent?
Bearing in mind that Ordinary Pony is a "silver-bordered" card:
Ordinary Pony's ability (in its Oracle text [C.R. 108.1]) expresses an ability that's linked to itself (C.R. 607.1c, 607.1). A creature "wa[s] put onto the battlefield with" that ability only if it was put onto the battlefield due to the same ability as the one referred to, rather than due to any other ability (including that of another Ordinary Pony, including a token or one that is represented by the same card but is a different object as far as the game is concerned) (C.R. 607.1; review C.R. 400.7).
In general, however, in a game allowing "silver-bordered" cards such as those in Unglued, Unhinged, and Unstable, the players in the game can agree on modifications to the comprehensive rules ("house rules") to accommodate situations that the comprehensive rules neither regulate nor answer and that are unique to such cards (see also C.R. 100.7). Although Mark Rosewater issues "rulings" on how certain game situations unique to such cards play out, such advice is no more or less valid than the "house rules" agreed to by the players (that is, such players can agree whether to adopt such "rulings" or not).

It's also the case that in silver-border land, the "spirit of the rules" becomes as relevant if not moreso than a strict reading of the rules.
Yep, that's mainly what I was wondering -- does the errata prevent Ordinary Pony from functioning like Felidar Guardian. peteroupc helped confirm that Ordinary Pony would function the same in these situations, but also noted the relevance of house rules in regards to Un-cards, which works for me as an answer.

Compare Ordinary Pony with Goblin Artisans. See also Kodama of the East Tree.
