This is just a sequence, but we can risk a Kyogre early too if your opponents bench is weak
C Common Melffy Catty X EARTH Level 2 [ BeastEffect ] ATK 200 DEF 200 If your opponent Normal or Special Summons a monster(s) (except during the Damage Step), or if an opponent's monster targets this card for an attack: You can return this card to the hand, then you can add 1 Beast monster from your Deck to your hand, except "Melffy Catty"
These are all 0 mana artifacts that tap to add a colour of mana
If the card is going to kill you no matter what, proceed to Priority 2 and see if you can stop them from getting there
Assembling those combos is a lot less reliable, so we dont have to balance them too harshly for limited or a competitive constructed environment
I think the deck will probably suck, but Gladiolus is probably good enough regardless of where the deck ends up
