Why does it matter if a card is rare

This process of swapping out weaker cards for more powerful or synergistic alternatives is how you begin to personalize your deck and raise its power level

For example, if you attack with a 5/5 creature with trample and your opponent blocks with a 2/2 creature, you can assign 2 damage to the blocker and 3 damage to the defending player

I think Tymna/Kraum is presented as getting all the good cEDH cards, and thats not really how it seems to me

This gives you plenty of ramp to make sure that you can cast it early, while also giving you access to the underplayed Archon of Valors Reach as a card that works great in concert with Angel of Destiny
