Tinker into fatty artifacts deck is tough to get to work and the pay-off don't justify the effort. The big artifact creatures have been removed for utility cards. This also freed up some of the untapped cards that synergised with the colossuses.

I'm trying red blue as a pinger theme which uses spells to stabilise and the pingers to maintain control/slowly win.

I've removed the planeswalkers as they don't fit in with the era that inspired the cube and are very powerful standalone cards. Sawtooth loon and quicksilver dagger are good signal cards for their respective archetypes.
