With one kick you're on par with other 2/2 Swampwalkers for three total mana, but at two or more kicks you're losing value when you end up with a 3/3 for five mana, or a 4/4 for six, etc
Liliana's Devotee, Liliana's Mastery, Cursecloth Wrappings, Gisa, the Hellraiser, and Death-Priest of Myrkul are additional lord effects that arent zombie creatures themselves
Make sure to carry playable cards with you Not carry playable cards, makes it hard to care about your trades I highly recommend grouping cards by color first then synergies ie elf cards that just happen to be next to eachother
The card selection is pretty good value given the drop will set you back $29.99 for the non-foil and $39.99 for the rainbow foil
Turn the life loss into a benefit with cards like Rowan, Scion of War or Vilis, Broker of Blood
