Time to take it to the test!
Build the thing and start playing

Thanks whisker for take your time and advice me !!!

70 cards for block + combo mill deck !?? it's not supoused that block decks work with 90 to have more endurance than their counterparts ?? i will try to go with less than or 80 cards, adding some stuff i belive i need. But anyways at least i will try once with 70 cards configuration. I will be so gratefull if you share your thoughs about my concerns in this matter.

It's Tappestry of blood a good card for this deck ??
