Sand Control

Probably the best Royal Guardian deck. Send these things off to die and then bring them back with arcane magics. Then bring back those magics with unholy and unspoken rituals.
There are many 1-of cards because you go through much of your deck each game.
Think in terms of bringing back multiple sentinels with shifting sands and set up applicable explorers/power turns(but turn 4 kiln is also worth the play)
Always remember to discard or mine canary(golem) a tribute for guardian before you start casting shifting sands.

Cards that this still wants (perform well for meta adjustments or substitutions) but are not in the current iteration for tinkering/space reasons:

More devotee of sands/ramp
1x more re-read (7th shifting sands but so few spells)
Conflag/equiv/bolt/purify (but sometimes a lone kiln will force play this and silence themselves)
1x more royal guardian(and 1x more tribute which gives this suprising resiliance against many things)
1x more mask - Although decking out is rare this ensures you can get your exponentially growing damage through in time.
1x more counterspell for boardwipes
Ancient defenses/1x old diogo/groundbreaker/other 4 drops- The 4 slot in this even deck is already overpopulated and relics are bad right now but this really stacks up the recurring summon bonuses from ancient defenses
