mtg cards like training grounds WINNING WITH GROUNDS! Rebel Stompy (Legacy Rebel Tribal with Mirror Entity MTG) and conquest Training Grounds (Card) | EDHREC

You get another card so that's mad card flow

Whenever a card is put into an opponent's graveyard from anywhere, put a +1/+1 counter on The Haunt of Hightower

Pandemonium and Warstorm Surge have one target each, while Impact Tremors has as many targets as we have opponents

There are multiple ways to stop opponents from attacking you: Mana tax cards (Ghostly Prison) that force the opponent to choose between casting spells and attacking you Damage reduction cards (Spike Weaver) that threaten to Fog oncoming damage, rendering attacks useless Rattlesnake cards (Archon of Justice) that threaten to blow up the attacking opponent's resources The sticking point is that these pillowfort cards are all visible on the board, so opponents know what could happen if they attack you and convinces them to go attack someone else

This is mana without any specific color, represented by a diamond-like shape in a gray circle
