Ok, I just think it's going to be pretty simple to create an eternal rainbow deck that blockades all damage.
Not necesarily, since there are 12 of these, putting all 12 in a single deck isnt wise, since you would also need the shields, plus everything else, creatures, spells, pillars, putting all 12 isnt that easy, plus you have to get lucky to draw one, even through hourglass.
now, the cost for putting all 12 on field isn't necesarily cheap or easy, especially if the opponent has a pulverizer and/or steals, explosions.
You also have to consider momentum, there are plenty of decks that use momentum incase going against such a defensive deck.
so i must disagree with this, its not necesarily going to block all damage, plus not all of them are damage blockers such as Holy pedestal which increases damage blocker by 1.
You have to consider that aswell, this series project is probably far from finished, as i said before, it needs cost balancing, mechanic balancing, conceptual development etc.
