I rarely see Dream Trawler outside of Cube - if you're an Azorius player, I recommend giving it a shot
Like Charizard, the Rainbow Rare VSTAR Arceus is among the rarest, having similar pull rates
Now, it may look resilient, but that is mostly an illusion
As another example, if at the start of turn six you have five cards in your inkwell and hold a two-drop, a three-drop, and a five-drop, then just cast your five-drop and dont add anything else to the inkwell at this point
It forces your opponent into a game of "block and lose their creature or let you cast a spell in their graveyard." Since it's a one-drop, you can get it down on the battlefield at any point, and potentially start taking advantage of it as soon as the second turn begins
This does leave you with a lower amount of regular lands lands that enter untapped
