There are obviously ways for you to still lose after doing this, but its going to be difficult
Sire of Stagnation Apparently, Sire of Stagnation was designed to be a card to be hated, although I cant find the source I heard this from now
Polluted Bonds Listed at: $7.50 An enchantment with a unique effect, this is the first time Polluted Bonds gets a reprint since Shadowmoor
Some examples include "Blaze Cannon" as Volcanic support In Name Only, Petit/Great Moth support, a Red-Eyes boss monster card (Dragoon) with almost limitless potential to the point where it is one of the most broken boss monster cards so far, etc
Honestly, though, none of the ones on offer really caught my eye anyway, so its no big loss in my book
You can, however, get lucky pulls that give you a strong enough deck to compete without spending money
