It's also possible to build a Zinnia Commander deck to maximize enter effects, and here's a few cards to help begin that process: Panharmonicon - this four-mana artifact has a static ability that says if a creature or artifact entering would trigger an ability of a permanent controlled by the player, that triggers twice instead
Repurposing Bay Repurposing Bay needs to be in an artifact-heavy Cube, making it rather restrictive, but an artifact-based Birthing Pod is incredibly sweet and will lead to some awesome decks
You could potentially be dealing 25+ damage to each opponent just on death triggers alone
It also helps that this is an Azorius precon, meaning it only uses white and blue mana, keeping things simple for new players, but the volume of colorless cards also means you should never be short of cards to play, so long as you have mana on the board
Unfortunately, because so many alternate versions of things are being released, its becoming more challenging for players to identify what cards are real and what are fake
