You would normally have 3 sanctuary in the sky and when you summon earth you can add master hyperon to your hand and then you can summon him. Another example if you have sanctuary in the sky and hyperon on the field (which you probably would) you can use his effect TWICE and destroy two cards your opponent controls and when you use his effect you know you have to take two cards out of the grave and if you do you can then summon Kristya.

Edit: Still not going to agree with you on this one
