When the promotion was run in North America earlier this year, the demand for the cards was high that stocks of it ran out almost immediately
For example, if you control Rin and Seri, Inseparabler as well as a permanent with "Each Dog you control enters with an additional +1/+1 counter on it" and you create a 1/1 Cat token, that Cat token will be a Dog Cat token and will enter with a +1/+1 counter on it, a woof, and a purr
One final thing to be aware of is that you cant put counters on a dead permanent , so playing a creature sweeper to draw off killing your own board only works if Weatherlight Compleated is either above 7 or under 4 counters
