skipping priority
I was playing a draft and I went to block a titanbones that was attacking ( alone) with a yuriko double strike effect I went to block with my Arcane Amphisbaena and I 4 mana up and Charge the sanctum in my hand but my priority was skipped after I had declared blockers which caused me to basically lose the game.

That's because Yuriko has more than one ability. You failed to account for this one:
"During combat, players can't cast spells or activate abilities that aren't mana abilities."
