The mat’s obvious, but it looks nice. But I think what might matter to readers is Magical Something’s Text

TDIL-ENSP1 Magical Something
Level 4 DARK Spellcaster-Type Effect Monster
ATK 1800
DEF 1300
Each time a Spell Card is activated, place 1 Spell Counter on this card when that Spell Card resolves. This card’s Level is increased by the number of Spell Counters on this card. You can remove 3 Spell Counters from this card, then target 1 Quick-Play Spell Card in your Graveyard; Set that card to your Spell & Trap Zone. You can only use this effect of “Magical Something” once per turn.
