mtg planeshift booster box In this Magic the Gathering strategy game MTG / Planeshift

Banishing items can help you deal damage or draw cards, plus it can be used to reduce the cost or increase the challenge strength of your most important cards

However, the effect counts only opponents (and not planeswalkers or battles) that you attacked with a creature when determining the bonus

Excalibur II This one-drop colorless life-gain caring Equipment with a cost of three will put a counter here for each life you gain and then the dork you equip gains a size boost equal to that charge count

Its easy to build an effective budget deck around it, just make sure you have common cheap defenders that no other deck wants, like Jaddi Offshoot or Walking Bulwark
