On top of that, some artifacts are specifically built for flexibility regardless of not only your mana base or color identity but also your deck's strategy
That, unfortunately, isnt a question I can answer
It turns out that when you have library manipulation and other high CMC cards in your deck the EtB trigger on this is pretty scary
This means that, on your turn, you can use it to attack an opponent without Flying or Reach creatures, and ensure the 4 damage to a player to activate the card draw on your end step
Then that five-cost Giant with flash and flying Thryx, the Sudden Storm gives our stuff with a five or more one less cost and then they cannot be countered too
It affects all creatures and players, but you should play it when it benefits you the most
