Overview
If you cast Primo, the Unbounded for X = N while you control Unbound Flourishing, Unbound Flourishing’s “double the value of X” trigger will trigger when you cast Primo and, assuming it resolves before Primo does, the spell’s X value becomes 2N. Primo’s oracle line “Primo enters with twice X +1/+1 counters on it” then uses that doubled X, so Primo will enter with 4N +1/+1 counters. Unbound Flourishing’s copy ability does not copy Primo’s triggered token-creation ability because that ability is a triggered ability (not an instant/sorcery cast or an activated ability with X in its activation cost); combat damage and the resulting triggers follow the normal combat damage rules , , . Also, the tokens created are 0/0 tokens whose base power is 0 per the applicable ruling, so they meet the “base power 0” condition for future triggers .
Step 1
You announce casting Primo and choose X = N, and you pay its mana cost 
(with X = N).
(with X = N).Step 2
Because you cast a permanent spell whose mana cost contains , Unbound Flourishing’s first triggered ability triggers on that casting (it’s a triggered ability that goes on the stack) .
, Unbound Flourishing’s first triggered ability triggers on that casting (it’s a triggered ability that goes on the stack) .Step 3
Assuming that triggered ability resolves before Primo resolves, it doubles the value of X for that spell, changing the spell’s X value from N to 2N.
Step 4
Primo resolves and enters the battlefield. Its ETB characteristic “enters with twice X +1/+1 counters” uses the current value of X (the doubled value 2N), so it enters with twice 2N = 4N +1/+1 counters.
Step 5
Later in combat, when one or more creatures you control with base power 0 deal combat damage to a player, the damage is assigned and dealt per the combat damage rules , .
Step 6
After that damage is dealt, Primo’s triggered ability triggers and goes on the stack per ; when it resolves it creates a 0/0 Fractal token and puts a number of +1/+1 counters on it equal to the damage dealt.
Step 7
Per the ruling about base power/toughness, those tokens are created with base power 0 (they are 0/0 by the creating effect) and then receive counters; their base power is 0 for purposes of future checks .
Resolution
When you cast Primo for X = N with Unbound Flourishing on the battlefield, Unbound Flourishing’s first ability triggers on casting and, if that trigger resolves before Primo resolves, it doubles the chosen X to 2N. Primo’s ETB formula (“enters with twice X +1/+1 counters on it”) then uses that doubled X, so Primo enters with 2 × (2N) = 4N +1/+1 counters. Unbound Flourishing’s copy ability doesn’t apply to Primo’s token-creating triggered ability because that ability is neither an instant/sorcery spell nor an activated ability with in its activation cost (Unbound’s copy clause only applies when you cast an instant or sorcery or activate an ability whose activation cost contains ) . Combat damage and the resulting trigger(s) from Primo’s ability are handled under the normal combat damage and trigger procedures , , . The tokens created are 0/0 and have a base power of 0 per the ruling on base power/toughness, so they satisfy Primo’s “base power 0” condition for future triggers .
