You have the effects of these two cards out of alignment with their themes within the lore of AST. Spire originally restored TP because it invigorated the body, so if you are going to throw on a card effect to increase max HP it would go onto Spire due to Spire's theme. Meanwhile Spear thematically is about being guided to victory as the Spear as a constellation is wielded by Halone. This is why the Spear increased Crit rate, because your strikes would be guided to the enemies weak points allowing you to land critical blows.
