serpent cards mtg of the Pass All cards will be carefully packed for safe transit MTGNexus - Jörmungandr, World Serpent

Tails: Once per turn, during your End Phase: Target 1 face-up monster your opponent controls

It would be like printing a Samurai deck

This can +2 to draw a card and scry two which is nice card flow, and then -3 to exile the top card of your library and then make a number of 1/1 flyers equal to the mana value, which is also very strong in Type Four with its elevated casting costs and low land count

You also get a discard and draw effect on ETB, so you improve your hand while also setting up delirium or graveyard synergies with relative ease

Given that nearly all of the value in MTG lies in rares and mythic rares, it means that Double Masters packs are technically worth more than normal, which is nice - but that worth should be for the players alone and not for Wizards of the Coast
