its not uncommon to see players cast spells for 10+ mana
But what if I told you there was a better way
Dark Beckoning Beast X DARK Level 2 [ FiendEffect ] ATK 0 DEF 0 When this card is Normal Summoned: You can add 1 "Uria, Lord of Searing Flames", "Hamon, Lord of Striking Thunder", or "Raviel, Lord of Phantasms", OR 1 card that mentions any of those cards, from your Deck to your hand, except "Dark Beckoning Beast"
May contain markings or highlighting, as well as stains, bent corners, or any other major defect, but the text is not obscured in any way
When an "Azamina" or "Sinful Spoils" card or effect is activated, except "Azamina Moa Regina" (Quick Effect): You can target up to 2 cards on the field
As such, your game plan should be making use of your Triamid card effects whenever possible , keeping board advantage as much as possible, and holding fast against whatever your opponent throws down
