The equip ability on its own, without outside help from cards like Leonin Shikari, cannot be activated at instant speed, so if you play an Artificers Hex on an equipment thats already attached to a creature, they will not be able to remove that equipment before they are in their main phase, guaranteeing you a dead creature
But how do I know that you can do all this
As with complexity, a card can be of a high rarity and not be wordy, it just doesn't often work the other way around
The four booster packs are a nice bonus, giving you a shot at pulling something rare while adding to your decks potential
I would not use needing to cast future splashes you may draw as anything more than a tiebreaker if you're really not sure what to do
You can play Atraxa as a poison-based deck, or a planeswalker deck, or even with a counter theme
