#14 Chainsaw Chainsaw is flying under the radar right now, but is going to be an absolute powerhouse in Voltron builds in Commander
Wild Slash is also burn based allowing you to add it to something else if you need to take out a really big thing
This is a mana more to use than Tinker but is much the same effect of sacrificing a type of card and replacing it with one you choose from your deck that is hopefully a substantial degree more powerful and expensive
These cards are effectively the same in terms of gameplay effect - although they may have different artwork - and are used to pay for other cards, activate effects and boost the power of your characters and leader during attacks
In fact, besides lands, there are only 15 non-artifact cards in Necron Dynasties
The card's ravenous trigger is harder to enact than most due to the double X casting cost, but it's a nice extra feature that could come in handy when you least expect it
