Discard subtheme

sacrifice feels oversupported. Recent prints allow to add a discard subtheme to this color pairing. Cards relevant for the theme:

1. Blazing rootwalla - payoff to get a free creature on discard
2. Ivora, insatiable heir - grows on discard and provides fuel with the blood tokens
3. Greasewrench goblin - 2/1 for one that discards
4. Marauding mako - grows, cycles, clean design
5. Bloodtithe harvester - value creature instead of redundant sacrifice payoff
6. Containment construct - turns discard into card advantage

Cut tokens

1. flayer husk - not worth a unique token
2. Oketra's monument - cuts an unique token and false signaling of the combo with kor skyfisher, which is often assiciated with this card.
3. hard evidence - let's try another crab: Canyon crab

Other changes

1. Vryn wingmare - instead of the monument
2. Fuel the flames - instead of a wordy flame sweep
3. Cut Dargo, the shipwrecker - too wordy and the sacrifice theme is already well supported
