Equestrian Princess Cadence - Beast/Fusion-7/Light/Effect  
Summon Requirement: 2+ “Equestrian” monsters.  
Effect: If this card is Fusion Summoned: you can target monsters your opponent controls up to the number of materials used to Fusion Summon this card; place 1 Love Counter on them. Monsters with Love Counters on them cannot declare an attack, change their battle position, or activate their effects. You can discard 1 card, then target 1 monster your opponent controls (Quick Effect); place 1 Love Counter on that card. You can only use each effect of ’Equestrian Princess Cadence” once per turn.
 
You can play this card freely on Duelingbook. I’ll even upload a few decklists that I’ve made just to get a basic feel of how the cards work. You’ll be able to change them to your liking.
