Shrine The Dam

I suggest 4xRecycle it seems to have zero downside it tosses out 3 grenadin it does a sac and it’s a safety net for out of control damage from Reactor Forge and since it’s fast you can use it as a offensive or as defensive block play you immediately get 9 Lifesteal of blockers if you have a Karvet in play (not that blocking is a prime play) but it’s sometimes required against X unit like Serasaur Bull or other

*Side note*
If you pull an Arach, Razorshaper or Scrapmetal Fury & have Karvet in play … it’s a nice trick to sac something first to get the bonus attack then drop either of those because it applies to the on summon (extra market cards or extra Razorbots) granted you need open spaces on the board for them to actually play(for the Razorbots)

So if you have one karvet active, you sac then drop Arach, Razorshaper u get 3 Razorbots vs just getting one … not to mention if you can hold one of these two cards in hand while one Arach, Razorshaper is active on board you can get those #’s even higher by sacrificing grenadins … but that’s pretty ridiculous.

It needs further testing but maybe you can see how I modified it I was missing a few of the legendary cards and I pared down on some of the higher cost units…my Market is a lot of experimentation (and there is lots of opportunity for change there)
