You probably wont get a winstreak with none monodeck in arena, except with maybe darkness or fire, and that's the fact we both know.... All I'm saying is "dude - if you want momentum, play momentum". What would you think about aether card that says: all of your immortal creatures ignore shield effects. My point is: if you want to burrow something, I still need the way to stop it. Look, quint + momentum + lava golem grants you 100% that your creature will: ignore shield and survive this turn. But you had to pay with 3 different elements for it (at least, you will need earth also for growth). Or overdrive a gravity dragon + momentum + quint = 4 cards, 2 elements (can do without OD). Titan, animate, quint = 3 cards, 2 elements.... Get my point so far? Truth, burrowed creature has 1/2 dmg, but you need: creature (shrieker, graboid, antlion) + Tunneling card = 2 cards, 1 element. OH, and btw: each time you'd quint/momentum a golem, you'd need a new quint card, and new momentum. Tunneling applies all your burrowed creatures. So, you need 2 cards 1st time, but later on its just planting graboids with nothing but the sundail to stop them.
