I remember being very excited to play with such a potent new card
Just stack up a few cantrips like Portent and Opt , then cast Elemental Eruption and copy it with Stella
(The exact restrictions are more specific, but thats the general idea.) Other formats, such as Modern and Legacy, dont rotate at all, meaning the pool of cards that you can choose from grows with each new set release
In this situation, we sacrifice Primus to Altar, which returns to the battlefield due to persist with no counters on it since the -1/-1 counter from persist and +1/+1 counter from Renata cancel each other out
Another problem that Pillow Fort decks typically run into is mass board resets like Cyclonic Rift, Austere Command, Bane of Progress and the like
Commander is a format that is open to many different strategies and understanding how to play is a beast compared to some other formats
